-/**
- * An optionally-reentrant lock for managing a contentious resource
- * 
- * <p>
- * Typically, a resource has a queue of actions that it executes in order, or it may only permit a
- * single pending action at any given time. If a task composed of many actions needs to ensure no
- * other actions are queued in between, it must use a lock. This is analogous to thread
- * synchronization. This can also be described as a queue to enter other queues.
- * 
- * <p>
- * Example:
- * 
- * <pre>
- * public CompletableFuture<Void> exampleLock1() {
- * 	AtomicReference<AsyncLock.Hold> hold = new AtomicReference<>();
- * 	return seq(TypeSpec.VOID).then((seq) -> {
- * 		lock.acquire(null).handle(seq::next);
- * 	}, hold).then((seq) -> {
- * 		doCriticalStuff().handle(seq::next);
- * 	}).then((seq) -> {
- * 		doMoreCriticalStuff().handle(seq::next);
- * 	}).then((seq) -> {
- * 		hold.release();
- * 		seq.exit();
- * 	}).asCompletableFuture().exceptionally((exc) -> {
- * 		hold.release();
- * 		return ExceptionUtils.rethrow(exc);
- * 	});
- * }
- * </pre>
- * 
- * <p>
- * Or more succinctly:
- * 
- * <pre>
- * public CompletableFuture<Void> exampleLock2() {
- * 	return lock.with(TypeSpec.VOID, null).then((hold, seq) -> {
- * 		doCriticalStuff().handle(seq::next);
- * 	}).then((seq) -> {
- * 		doMoreCriticalStuff().handle(seq::next);
- * 	}).asCompletableFuture();
- * }
- * </pre>
- * 
- * <p>
- * Re-entry is supported via a {@link Hold}. A method that offers re-enter into a critical section
- * must accept a {@link Hold} parameter. Generally, the caller indicates the callee should reenter
- * by passing the current hold. It then forwards it to the lock, via {@link #acquire(Hold)} or
- * {@link #with(TypeSpec, Hold)}. The hold must be a reference to the current hold or null. A hold
- * from another lock cannot be used for re-entry. If it is null, normal behavior is applied and the
- * queue is served in FIFO order. If it is a reference to the current hold, the callback is executed
- * immediately. Reentrant holds must be released in the reverse order of acquisition.
- * 
- * <pre>
- * public CompletableFuture<Void> canReenter(Hold reenter) {
- * 	return lock.with(TypeSpec.VOID, reenter).then((hold, seq) -> {
- * 		doCriticalStuff();
- * 	}).asCompletableFuture();
- * }
- * 
- * public CompletableFuture<Void> exampleLock3() {
- * 	return lock.with(TypeSpec.VOID, null).then((hold, seq) -> {
- * 		canReenter(hold).handle(seq::next);
- * 	}).then((seq) -> {
- * 		doMoreCriticalStuff().handle(seq::next);
- * 	}).asCompletableFuture();
- * }
- * </pre>
- * 
- * <p>
- * The implementation is based on a queue a queue of futures. The {@link #acquire(Hold)} task
- * completes when the lock is available or if re-entry is possible. {@link Hold#release()} is not a
- * task, but it must be called to ensure the next handler is invoked. If a hold is forgotten, e.g.,
- * a sequence fails to release it, deadlock will likely occur. In some circumstances, deadlock is
- * detected, causing all queued actions (current and future) to complete exceptionally with an
- * {@link IllegalStateException}. Deadlock detection is a debugging feature. A programmer cannot
- * rely on it for error recovery. If the exception is thrown, it indicates a serious flaw in the
- * program which cannot be corrected at runtime.
- * 
- * <p>
- * The above examples demonstrate two critical actions, because in general, a single action is
- * atomic. This lock <em>does not</em> protect against the usual multi-threaded hazards. Because any
- * queue may be served by a multi-threaded executor, shared resources must be protected using
- * standard synchronization primitives, e.g., the {@code synchronized} keyword. Resources whose
- * methods provide futures are better protected using this lock, because a standard {@link Lock}
- * will block the calling thread -- perhaps stalling a queue's executor -- whereas this lock permits
- * the thread to execute other actions.
- * 
- * @note This implementation offers little protection against double locking, or gratuitous
- *       releasing.
- * @note As an asynchronous task, {@link #acquire()} returns immediately, but the future does not
- *       complete until the lock is acquired.

 /**
- * A wrapper for Java's {@link CompletableFuture} that provides additional fluency
- * 
- * <p>
- * The {@link CompletableFuture} class is very useful for organizing asynchronous tasks into tidy
- * sequences. See {@link CompletableFuture#thenCompose(Function)} for more information, though
- * better examples are available in other online resources.
- * 
- * <p>
- * These utilities seek to ease some operations, e.g., loops, and provide some control of execution
- * in sequences not otherwise given by Java's futures. While some verboseness is eliminated, these
- * utilities have tradeoffs. They interoperate, permitting use of each according to circumstances
- * and taste.
- * 
- * <p>
- * Additional conveniences allow Java's non-blocking IO to interoperate more closely with futures.
- * See {@link AsynchronousByteChannel}. The "nio" API predates {@link CompletableFuture}, so they
- * cannot readily interact. They use {@link CompletionHandler}s instead of futures. This class
- * provides API wrappers that return {@link CompletableFuture}s.
- * 
- * <p>
- * An asynchronous method is one that returns control immediately, and may promise to provide a
- * completed result at some future time. In the case of computation, the method may launch a thread
- * or queue the computation on an executor. In the case of non-blocking IO, the method may queue a
- * handler on an asynchronous channel. The method is said to "promise" a completed result. It
- * instantiates the promise and arranges its fulfillment. It can then return control immediately by
- * returning the corresponding "future" object. When the promise is fulfilled, the result is stored
- * in the future object, optionally invoking a callback.
- * 
- * <p>
- * Java implements this pattern in {@link CompletableFuture}. Java does not provide a separate class
- * for the promise. The asynchronous method instantiates the completable future, arranging for its
- * completion, and immediately returns it to the caller. Anything with a referece to the future may
- * complete it. The "promise" and "future" objects are not distinct. Note that
- * {@link AsynchronousByteChannel} does provide methods that return {@link Future}, but the
- * underlying implementation is not a {@link CompletableFuture}, so it cannot accept callbacks.
- * 
- * <p>
- * There are generally two ways the caller can consume the value. The simplest is to wait, by
- * blocking, on the result. This defeats the purpose of asynchronous processing. For example:
- * 
- * <pre>
- * System.out.println(processAsync(input1).get());
- * System.out.println(processAsync(input2).get());
- * </pre>
- * 
- * <p>
- * This block is not any more efficient than the following sequential program:
- * 
- * <pre>
- * System.out.println(processSync(input1));
- * System.out.println(processSync(input2));
- * </pre>
- * 
- * <p>
- * In fact, it may be worse from the overhead of multi-threading, queueing, scheduling, etc. To take
- * advantage of multi-threaded executors, processing should be performed in parallel when possible.
- * For example:
- * 
- * <pre>
- * CompletableFuture<Long> future1 = processAsync(input1);
- * CompletableFuture<Long> future2 = processAsync(input2);
- * System.out.println(future1.get());
- * System.out.println(future2.get());
- * </pre>
- * 
- * <p>
- * Now, both inputs can be processed simultaneously. The other way to consume the value is via
- * callback. This elegant option may seem complex. It is especially effective when the calling
- * thread cannot or should not block. For example:
- * 
- * <pre>
- * processAsync(input1).thenAccept((result1) -> {
- * 	System.out.println(result1);
- * });
- * processAsync(input2).thenAccept((result2) -> {
- * 	System.out.println(result2);
- * });
- * </pre>
- * 
- * <p>
- * Now, both inputs can be processed simultaneously, and each result is printed the moment it
- * becomes available. Another notable difference: If processing of input2 finishes first, it can be
- * printed without waiting on input1. Furthermore, the calling thread is not blocked. Long chains of
- * asynchronous callbacks, however, an become difficult to manage.
- * 
- * <p>
- * Suppose a program must fetch a list of integers from a storage system, then process each entry by
- * submitting it to a remote service, and finally aggregate the results with a given initial value.
- * 
- * <p>
- * The traditional implementation might look like this:
- * 
- * <pre>
- * public int doWork(int start) {
- * 	Storage store = connectStorage(ADDR1);
- * 	Service serve = connectService(ADDR2);
- * 	List<Integer> list = store.fetchList();
- * 	int sum = start;
- * 	for (int entry : list) {
- * 		sum += serve.process(entry);
- * 	}
- * 	store.close();
- * 	serve.close();
- * 	return sum;
- * }
- * </pre>
- * 
- * <p>
- * Now, suppose the connect methods, the fetch method, and the process method all perform their work
- * asynchronously, providing results via futures. The implementation ought to provide for parallel
- * execution. The chain of asynchronous tasks essentially becomes a composite task, itself
- * implementing the future pattern. One scheme is to create a class extending
- * {@link CompletableFuture} and containing all callback methods in the chain:
- * 
- * <pre>
- * class FetchAndProcess extends CompletableFuture<Integer> {
- * 	Storage storage;
- * 	Service service;
- * 	AtomicInteger sum = new AtomicInteger();
- * 
- * 	FetchAndProcess(int start) {
- * 		sum = start;
- * 		connectStorage(ADDR1).handle(this::storageConnected);
- * 	}
- * 
- * 	Void storageConnected(Storage s, Throwable exc) {
- * 		if (exc != null) {
- * 			completeExceptionally(exc);
- * 		}
- * 		else {
- * 			storage = s;
- * 			connectService(ADDR2).handle(this::serviceConnected);
- * 		}
- * 		return null;
- * 	}

- * </pre>
- * 
- * <p>
- * The asynchronous method then just instantiates the class and returns it. The final callback in
- * the chain must call {@link CompletableFuture#complete(Object)}. The main deficit to this method
- * is that the operational steps are buried between method declarations and error checks. Also,
- * because the method must return {@link Void}, not just {@code void}, all the methods must return
- * {@code null}. Furthermore, errors that occur in the callback methods do not get communicated to
- * the caller of {@code doWork}. Additional try-cache blocks would be required.
- * 
- * <p>
- * Lambda functions could be substituted for method references avoiding the class declaration, but
- * that would result in nesting several levels deep -- at least one level per callback in the chain.
- * To avoid nesting, Java provides {@link CompletableFuture#thenCompose(Function)}, which provides a
- * fairly elegant implementation:
- * 
- * <pre>
- * public CompletableFuture<Integer> doWork(int start) {
- * 	AtomicReference<Storage> store = new AtomicReference<>();
- * 	AtomicReference<Service> serve = new AtomicReference<>();
- * 	AtomicInteger sum = new AtomicInteger(start);
- * 	return connectStorage(ADDR1).thenCompose((s) -> {
- * 		store.set(s);
- * 		return connectService(ADDR2);
- * 	}).thenCompose((s) -> {
- * 		serve.set(s);
- * 		return store.get().fetchList();
- * 	}).thenCompose((list) -> {
- * 		List<CompletableFuture<Void>> futures = new ArrayList<>();
- * 		for (int entry : list) {
- * 			futures.add(serve.get().process(entry).thenAccept((result) -> {
- * 				sum.addAndGet(result);
- * 			}));
- * 		}
- * 		return CompletableFuture.allOf(futures.toArray(new CompletableFuture[list.size()]));
- * 	}).thenApply((v) -> {
- * 		store.get().close();
- * 		serve.get().close();
- * 		return sum.get();
- * 	});
- * }
- * </pre>
- * 
- * <p>
- * This does have a couple notable deficits, though. First, the {@code return} keyword is almost
- * abused. The callbacks are defined inline as if they were simply actions within the method. In
- * this context, {@code return} can become misleading, because that is not the point where the
- * method terminates with a result, but rather the point where the action provides the next
- * subordinate asynchronous task in the chain. Second, not all the actions are presented at the same
- * nesting level, even though they reside in the same sequence. Because of this, it's not
- * immediately obvious that, e.g., {@code connectStorage} precedes {@code connectService}, or
- * perhaps a more subtle example, that {@code process} precedes {@code sumAndGet}.
- * 
- * <p>
- * With the utilities, we can write this sequence a little differently. The goal is to mimic
- * sequential programming not just in its appearance, but also in its control structure:
- * 
- * <pre>
- * public CompletableFuture<Integer> doWork(int start) {
- * 	AtomicReference<Storage> store = new AtomicReference<>();
- * 	AtomicReference<Service> serve = new AtomicReference<>();
- * 	AtomicInteger sum = new AtomicInteger(start);
- * 	return sequence(TypeSpec.INT).then((seq) -> {
- * 		connectStorage(ADDR1).handle(seq::next);
- * 	}, store).then((seq) -> {
- * 		connectService(ADDR2).handle(seq::next);
- * 	}, serve).then((seq) -> {
- * 		store.get().fetchList().handle(seq::next);
- * 	}, TypeSpec.obj((List<Integer>) null)).then((list, seq) -> {
- * 		AsyncFence fence = new AsyncFence();
- * 		for (int entry : list) {
- * 			fence.include(sequence(TypeSpec.VOID).then((seq2) -> {
- * 				serve.get().process(entry).handle(seq2::next);
- * 			}, TypeSpec.INT).then((result, seq2) -> {
- * 				sum.addAndGet(result);
- * 				seq2.exit();
- * 			}).asCompletableFuture());
- * 		}
- * 		fence.ready().handle(seq::next);
- * 	}).then((seq) -> {
- * 		store.get().close();
- * 		serve.get().close();
- * 		seq.exit(sum.get());
- * 	}).asCompletableFuture();
- * }
- * </pre>
- * 
- * <p>
- * The implementation is slightly longer because the body of the for-loop is also implemented as a
- * two-step sequence instead of using {@link CompletableFuture#thenAccept(Consumer)}. First, notice
- * that the sequence starts with a call to {@link #sequence(TypeSpec)}. This essentially declares an
- * inline asynchronous method whose result will have the given type. This mimics a standard method
- * declaration where the type is given first; whereas
- * {@link CompletableFuture#thenCompose(Function)} implicitly takes the return type of the final
- * callback.
- * 
- * <p>
- * Second, notice that the callback is given a reference to the sequence. Technically, this is just
- * a contextual view of the sequence's handlers. It implements two methods which may be passed to
- * {@link CompletableFuture#handle(BiFunction)}. This constitutes a major difference from the
- * composition pattern. Instead of returning a {@link CompletableFuture} to wait on, the action must
- * explicitly call {@code handle(seq::next)}. This permits the execution of additional code after
- * calling the asynchronous method in parallel. While this provides more flexibility, it also
- * provies more opportunities for mistakes. Usually, passing or calling the handler is the last line
- * in a callback action. See {@link AsyncSequenceHandlerForRunner#next(Void, Throwable)} and
- * {@link AsyncSequenceHandlerForProducer#next(Object, Throwable)}.
- * 
- * <p>
- * Third, notice that the call to {@code connectStorage} is now at the same nesting level as
- * {@code connectService}. This keeps the operative parts of each action immediately visible as they
- * are left justified, have the same indentation, and are not preceded by {@code return}. However,
- * it is easy to forget {@link CompletableFuture#handle(BiFunction)}.
- * 
- * <p>
- * Fourth, notice that each action is always separated by a call to
- * {@link AsyncSequenceWithoutTemp#then(AsyncSequenceActionRuns)} or one of its variants in
- * {@link AsyncSequenceWithTemp}. This generally means the lines between actions can be ignored. In
- * the composition pattern, the reader would need to see that the final action is given by
- * {@link CompletableFuture#thenApply(Function)} in order to properly comprehend the return
- * statement properly. It is not another asynchronous method as in the previous actions. Rather it
- * is the final result. The line between actions in the sequence pattern cannot be ignored when a
- * value is passed from one action directly to the following action. The call to {@code then}
- * includes the type of the passed value. Worse yet, this sometimes requires casting {@code null} to
- * an arbitrary type. In the example, a list is retrieved in the third action and processed in the
- * fourth. To specify the type, {@code null} is cast to
- * {@link List}{@code <}{@link Integer}{@code >} and passed to {@link TypeSpec#obj(Object)}. The
- * list retrieved by {@code fetchList} is received in the following action's first parameter
- * ({@code list}) of its lambda function.
- * 
- * <p>
- * Fifth, notice the use of {@link AsyncFence}. This convenience class does essentially the same
- * thing as the composition and class patterns did, but provides more meaningful method names and a
- * more succinct syntax.
- * 
- * <p>
- * Finally, notice the call to to {@link AsyncSequenceHandlerForRunner#exit(Object)} passing the
- * final result of the sequence. Requiring this is a bit of a nuisance, but it makes clear what the
- * result of the sequence is. Furthermore, {@code exit} can be called by any action, not just the
- * final one. In the composition pattern, execution cannot be truncated except by error handling. In
- * the sequence pattern, any action can terminate the sequence and "return" the result. Every action
- * must either call or pass one of these handlers or the sequence will abruptly halt. Also, some
- * action, usually the final one, must pass or invoke the {@code exit} handler. If the final action
- * uses {@code next}, the sequence will "return" {@code null}. In summary, {@code next} passes a
- * value to the following action while {@code exit} passes a value as the sequence result, skipping
- * the remaining actions. The result of composed sequence of actions is communicated via its own
- * completable future. This future is obtained via {@link AsyncSequenceWithoutTemp#finish()}. Note
- * that a sequence whose final action produces a temporary value does not yield a completable
- * future.
- * 
- * <p>
- * Java's built-in mechanisms provide for error handling. Usually invoking
- * {@link CompletableFuture#exceptionally(Function)} on the result of
- * {@link AsyncSequenceWithoutTemp#finish()} is sufficient. To illustrate, the two connections from
- * the example are assuredly closed by appending a call to {@code exceptionally}:
- * 
- * <pre>
- * return sequence(TypeSpec.INT).then((seq) -> {
- * 	// ...
- * }).asCompletableFuture().exceptionally((exc) -> {
- * 	if (store.get() != null) {
- * 		store.get().close();
- * 	}
- * 	if (serve.get() != null) {
- * 		serve.get().close();
- * 	}
- * 	return ExceptionUtils.rethrow(exc);
- * });
- * </pre>
- * 
- * <p>
- * If errors must be handled in a more granular fashion, consider invoking
- * {@link CompletableFuture#exceptionally(Function)} on the appropriate asynchronous task before
- * calling {@link CompletableFuture#handle(BiFunction)}. For example:
- * 
- * <pre>
- * store.get().fetchList().exceptionally((exc) -> {
- * 	if (exc instanceof ListNotFoundException) {
- * 		return DEFAULT_LIST;
- * 	}
- * 	return ExceptionUtils.rethrow(exc);
- * }).handle(seq::next);
- * </pre>
- * 
- * <p>
- * Alternatively:
- * 
- * <pre>
- * store.get().fetchList().handle(seq::next).exceptionally((exc) -> {
- * 	if (exc instanceof ListNotFoundException) {
- * 		seq.next(DEFAULT_LIST);
- * 	}
- * 	else {
- * 		seq.exit(exc);
- * 	}
- * 	return null;
- * });
- * </pre>
+ * Some conveniences when dealing with Java's {@link CompletableFuture}s.

-/**
- * An interface for type specification in sequences
- *
- * This is just fodder for Java's generic type system. Sometimes it is not intelligent enough to
- * resolve a type parameter, especially when passing a lambda function. A workaround, albeit
- * hackish, is to add an unused argument to aid resolution. Take for example, the utility method
- * {@link AsyncUtils#sequence(TypeSpec)}. It returns a {@link AsyncSequenceWithoutTemp}{@code <R>}.
- * Were it not for the argument {@code TypeSpec<R> type}, Java could only resolve {@code <R>} by
- * assigning the sequence to a temporary variable. This would require an extra line for the
- * assignment, including the full specification of the type, e.g.:
- * 
- * <pre>
- * AsyncSequenceWithoutTemp<Integer> s = sequence().then((seq) -> {
- * 	// Do stuff
- * });
- * return s.asCompletableFuture();
- * </pre>
- * 
- * However, this makes the definition exceedingly verbose, and it exposes the implementation
- * details. While the unused argument is a nuisance, it is preferred to the above alternative. Thus,
- * the static methods in this class seek to ease obtaining an appropriate {@code TypeSpec}. Several
- * primitive and common types are pre-defined.
- * 
- * This interface is not meant to be implemented by any classes or extended by other interfaces. The
- * runtime value of a {@code TypeSpec} argument is always {@link #RAW}. The arguments only serve a
- * purpose at compile time.
- * 
- * TODO: Look at TypeLiteral instead....

-/**
- * A set of enumeration constants encoded using bits
- * 
- * All constants in the set must belong to the same enumeration called the "universe." The
- * enumeration must implement {@link BitmaskUniverse}, so that each constant provides its mask bit.
- * This is essentially a "set" abstraction on the idiom of using "flag" bits to represent the
- * present or absence of each element.
- * 
- * It is highly recommended that each constant's mask have a population of one bit. At the very
- * least, each should have one unique bit. Constants which represent combinations of other flags are
- * allowed, but they should be documented. Defining such combinations may produce surprising
- * behavior from the perspective of the {@link Set} interface. For instance, consider constants
- * {@code VAL_A}, {@code VAL_B}, and {@code VALS_A_B}. Adding {@code VAL_A} will cause no surprise,
- * but subsequently adding {@code VAL_B} will cause {@code VALS_A_B} to materialize, even though it
- * was never added explicitly. So long as the calling methods do not expect strict set behavior,
- * this is OK. If there exists a constant which defines zero flags, then the behavior is undefined.
- * In general, the element will always be present, even though {@link #isEmpty()} may return
- * {@code true}.
