Add a coroutine_wrapper decorator
This decorator checks for the coroutine=True keyword arg and wraps the result of the function call in a coroutine if it isn’t. This allows to have constructs like: @coroutine_wrapper def toto(xmpp, *, coroutine=False): if xmpp.cached: return xmpp.cached else: return xmpp.make_iq_get().send(coroutine=coroutine) @asyncio.coroutine def main(xmpp): result = yield from toto(xmpp, coroutine=True) xmpp.cached = result result2 = yield from toto(xmpp, coroutine=True) If the wrapper wasn’t there, the second fetch would fail. This decorator does not do anything if the coroutine argument is False.
