asyncio currently uses iterable coroutine directly to wrap awaitables with __await__ methods. This leads to unnecessary special casing and is confusing as asyncio does not supports using yield from now so it should not be used internally too. This will avoid checking for generators everywhere in public APIs (TBD for different issue).
