[Python-Dev] [Python-ideas] PEP 3156 - Asynchronous IO Support Rebooted

[Jonathan Slenders]

As far as I understand, "yield from" will always work, because a Future
object can act like an iterator, and you can delegate your own generator to
this iterator at the place of "yield from".
"yield" only works if the parameter behind yield is already a Future
object. Right Guido?

In case of sleep, sleep could be implemented to return a Future object.
