Re: [Python-Dev] Hooking into super() attribute resolution

Could the same result be achieved by hooking the MRO that super uses and returning a list of proxy objects? And then wouldn't you only really need a __getattribute__ that doesn't recurse (__getlocalattribute__)? The end result may be conceptually simpler, but you've thought through the edge case

+1. And maybe amend PEP 11 to specify "whose extended support phase does not expire within 6 months of release"? (I picked 6 for no particular reason.) I don't see any good reason for Python to support an OS that Microsoft doesn't, but once 3.4.0 has been released with XP support it can't really

Re: [Python-Dev] Adding Python scripts to PATHEXT on Windows

Any chance of this being made optional when installing? It provides no benefit for people who prefer to associate scripts with an editor and may be a source of confusion/complaints. Env var changes typically require a reboot to take full effect, which I've also seen cause confusion. Also, it s
