In Guido's keynote at PyCon 2013, apparently he talked about adding an<br>
async I/O module to Python 3.4. It looks like his slides can be viewed<br>
here:<br>

...while this is the PEP he's talking about:<br>
<br>
<a href="http://www.python.org/dev/peps/pep-3156/" target="_blank">http://www.python.org/dev/peps/pep-3156/</a><br>
<br>
At first glance, the proposed reactor API looks very much like Twisted's<br>
(or, to be fair, GTK's, or possibly any number of other async event loop<br>
I'm less familiar with) but rather than Deferreds and callbacks, the API<br>
will be based around Futures (similar, but not identical, to Python<br>
3.2's concurrent.futures.Future class), and an inlineCallbacks-style<br>
decorator for generators.<br>
<br>
I know Deferreds are awesome, and I don't know much about Futures (and<br>
I know Twisted core developers have given negative reviews of<br>
other Deferred/Promise/Future implementations in, say, JavaScript<br>
libraries before), and inlineCallbacks seems to have a negative<br>
reputation among experienced Twisted users. Is there anybody on this<br>
list who knows more about this new PEP (maybe somebody who's at PyCon<br>
and saw the talk in person) who can give us an informed comparison with<br>
the current state of Twisted?<br>
