I'm not sure this is an improvement over having yield() return a
tuple. I guess that discussion must've taken place on the developers
list.

The signature inversion thing makes me uneasy. Although I don't yet
have a definite case in mind, I worry that would make it difficult to
synthesize a coroutine as a helper object in generic code that needs
to deal with arbitrary signatures.
