You can also use a trampoline of some kind to relay values back and forth between generators, to get something symmetric. Yes, that's of course how coroutine frameworks were done long before "yield from" appeared and how Trollius works now.

No, what I mean is that if you want to send stuff back and forth between two particular coroutines in a symmetric way, you can write a specialised scheduler that just handles those coroutines.

If you want to do that at the same time that other things are going on, I think you're better off not trying to do it using yield. Use a general scheduler such as asyncio, and some traditional IPC mechanism such as a queue for communication.
