[python-tulip] Reflection on @asyncio.coroutine funs

[Tobias Oberstein]

Hi,

I have noticed that `inspect.getargspec` won't return useful information 
on functions decorated with `@asyncio.coroutine`.
(Sidenote: same with Twisted's `@inlineCallbacks`)
However, `inspect.signature` from

http://www.python.org/dev/peps/pep-0362/

 _does_ work (means: returns the actual function signature).

Will this be made available on Python 2, or are there fundamental 
reasons this won't work out?
