[issue24017] Implemenation of the PEP 492 - Coroutines with async and await syntax

[Stefan Behnel]

Stefan Behnel added the comment:

Could we have type slots for the new special methods? Otherwise, implementing the protocol in C would be fairly inefficient, especially for async iteration.

I'm asking because Cython's generator type is not Python's generator type, but implementing the rest of the proposed protocol doesn't seem to be all that difficult.
