/**
 * An extension to the {@link ForkableSink:class} that immediately
 * queues the entire contents of whatever has been previously consumed.
 *
 * @group Sinks
 * @see {@link ForkableReplayStream:class}
 * @example
 * ```
 * const forkable = new ForkableReplaySink<number>()
 * const writable = new WritableStream(forkable)
 * await fromCollection([1, 2, 3, 4, 5, 6, 7]).pipeTo(writable)
 * ```
 *
 * Now the stream has finished, if we fork from it we'll
 * receive the entire events that were published to it.
 *
 * ```
 * await forkable.fork().pipeTo(write(console.info))
 * // 1
 * // 2
 * // 3
 * // 4
 * // 5
 * // 6
 * // 7
 * ```
