Hi,
I'm still trying to understand how the PEP 3152 would impact asyncio.
Guido suggests to replace "yield from fut" with "cocall fut()" (add
parenthesis) and so add a __cocall__() method to asyncio.Future.
Problem: PEP 3152 says "A cofunction (...) does not contain any yield
or yield from expressions". Currently, Future.__iter__() is
implemented using yield:
def __iter__(self):
if not self.done():
self._blocking = True
yield self # This tells Task to wait for completion.
assert self.done(), "yield from wasn't used with future"
return self.result() # May raise too.
>From my understanding, the PEP 3151 simply does not support
asyncio.Future. Am I right?
How is it possible to suspend a cofunction if it's not possible to use yield?
If waiting for a future in a cofunction is not supported, the PEP 3151
is useless for asyncio, since asyncio completly relies on futures.
