The more I hear about this topic, the more I think that `await`, `yield` and `yield from` should all be banned from occurring in all comprehensions and generator expressions. That's not much different from disallowing `return` or `break`.
IIUC this would essentially mean rejecting PEP 530. What do you think about banning `await`, `yield` and `yield from` only from generator expressions? Comprehensions can be fixed (just make them equivalent to for-loops without leaks as discussed). -- Ivan
