a,This class is *almost* compatible with concurrent.futures.Future.

    Differences:

    - This class is not thread-safe.

    - result() and exception() do not take a timeout argument and
      raise an exception when the future isn't done yet.

    - Callbacks registered with add_done_callback() are always called
      via the event loop's call_soon().

    - This class is not compatible with the wait() and as_completed()
      methods in the concurrent.futures package.

    (In Python 3.4 or later we may be able to unify the implementations.)

Chain two futures so that when one completes, so does the other.

    The result (or exception) of source will be copied to destination.
    If destination is cancelled, source gets cancelled too.
    Compatible with both asyncio.Future and concurrent.futures.Future.
