The typing module defines the Generator type for return values of generator functions. It is a subtype of Iterable and it has additional type variables for the type accepted by the send() method and the return type of the generator:

* Generator, used as Generator[yieldtype, sendtype, returntype]

Is this meant to accept only Python generators, or any kind of object that implements the coroutine protocol? I'm asking because asyncio currently suffers from an annoying type check here, so I'd like to avoid that this problem keeps popping up again in other places.
