what would a 3rd party module need to implement to provide such a
thing? Can any of the non-IO related parts of asyncio be reused for
the purpose, or must the 3rd party module implement everything from
To me, this is an important question, as it cuts directly to the heart
of the impression people have that coroutines and async are "only for
I'd be interested in writing, for instructional purposes, a toy but
