Not sure I fully get it:
Twisted's `inlineCallback` use regular raise for exceptions, but a special
`returnValue` function for returning
https://github.com/tavendo/AutobahnPython/blob/master/examples/twisted/websocket/slowsquare/server.py#L36
Is that a third alternative? [not a rhetorical question! ;)]
No, that function raises an exception. The disadvantage (in my mind)
over just using a raise statement is that the control flow is clear to
even the dumbest "static analysis" code (like Emacs' python-mode).
Ahh. Yes.

[Sorry, I should have had a look into `returnValue` myself ..]
It's just sugered up in Twisted .. and one could simply do
def returnValue(value):
raise asyncio.Result(value)
on top of Trollius.
But I agree on the control flow thing.
Thanks again,
