That's another good point that I forgot to add to the list.
Thanks for bringing this up.

You'll have to use a wrapper that will do the following:
async def foo():
return 'spam'
@asyncio.coroutine
def bar():
what = yield from foo.__await__(foo, *args, **kwargs)
# OR:
what = yield from await_call(foo, *args, **kwargs)
Thanks,
