Please, Martin, I dislike this idea as much as you do. (There was no -1 from me, though, because I don't work in the context of the claimed use cases at all, but lots of people obviously find them persuasive.) But in respect of myth-spreading, the problem with the PEP is the polemic tone. (Yeah, I've seen Armin's claim that it's not polemic. I disagree.) The unqualified claims that "2to3 is insufficient" and the PEP will "enable side-by-side support" of Python 2 and Python 3 by libraries are too extreme, and really unnecessary in light of Guido's logic for acceptance. As far as I can see, like 2to3, like u()/b(), this PEP introduces a device that will be the most *convenient* approach for *some* use cases. If it were presented that way, with recommendation for its use restricted to the particular intended use case, I don't think it would have a huge effect on people's perception of the difficulty of porting in general, including multiversion support including 2.5. If others want to use it, even though you and I think that's a bad idea, well, we can blog, and "consenting adults" covers those users. On the other hand, implementation of the PEP itself should have a positive effect on the community's perception of python-dev's responsiveness to its pain. Ie, a lot of us feel strongly that this is the wrong thing to do in principle -- but we're gonna do it anyway, because part of the community wants it. So, let's work on integrating this PEP into the more general framework of recommendations for porting Python 2 code to Python 3 and/or developing libraries targeting both. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
