Hi Victor,

From my understanding, the PEP 3151 simply does not support asyncio.Future. Am I right?

Greg wants to implement cocall on futures. This way you'll be able to write

cocall fut()  # instead of "await fut"

So you will have to use "()"

Another problem is functions that return future:

def do_something(): ... return fut

With Greg's idea to call it you would do:

cocall (do_something())()

That means that you can't refactor your "do_something" function and make it a coroutine.
