As a general comment, I like the direction this has moved in. In particular, I like the fact that ABCs can be registered after the fact (as Talin describes it, "post-hoc classification". > ABCs vs. Duck Typing This remains my key concern. The PEP nicely addresses the issue as far as core Python is concerned, but I'd be happier with some style recommendations for 3rd party frameworks clarifying that they should also avoid taking the "stick" approach. OTOH, we've had interface implementations, and heavy users of them (e.g. zope.interface and Twisted) for ages now, and the world hasn't ended, so I guess there's no reason to assume that people won't use ABCs sensibly, too. Overall, then, I'm moving towards a +1 (or at least a +0.5...)
