I'd be very grateful if anyone can point out if my understanding of the above is incorrect. Private email is fine if you prefer not to post to the list.

It is correct. While 'yield from coro()', where 'coro()' is an 'async def' coroutine would make sense in some contexts, it would require coroutines to implement the iteration protocol. That would mean that you could write 'for x in coro()', which is meaningless for coroutines in all contexts. Therefore, coroutines do not implement the iterator protocol. Yury
