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.
