[issue36921] Deprecate yield from and @coroutine in asyncio

[Nathaniel Smith]

Nathaniel Smith  added the comment:

@types.coroutine is still useful as a tool for writing "foundation" coroutines 
that directly interact with the coroutine runner, e.g.:

https://github.com/python-trio/trio/blob/94562c54d241859eb05ed85c88fd6073d6752ff6/trio/_core/_traps.py#L12-L21

https://github.com/dabeaz/curio/blob/27ccf4d130dd8c048e28bd15a22015bce3f55d53/curio/traps.py#L28-L36

So I think it's only @asyncio.coroutine that should be deprecated.

Josh Rosenberg  added the comment:

Was this supposed to deprecate using types.coroutine as a decorator as well? 
Because that's not clearly documented, which means people can still use it to 
make generator-based coroutines without async def.
