/**
 * @assertion Stream<T> skip(int count)
 *    Skips the first count data events from this stream.
 *    Returns a stream that emits the same events as this stream would
 * if listened to at the same time, except that the first [count]
 * data events are not emitted.
 * The returned stream is done when this stream is.
 *    If this stream emits fewer than [count] data events
 * before being done, the returned stream emits no data events.
 * @description Checks that errors in the input stream are propagated to the
 * returned stream.
