Raymond Hettinger added the comment: I think some variant of these patches was rejected before and part of these reason had to do with subtle semantic changes when switching from an old-style class (inheriting from UserDict) to a new-style class (inheriting from dict). There were also some concerns that it could break code currently relying on isinstance(x, UserDict).
IMO, this just isn't work it. The os.environ use cases are not typically the performance critical part of a script. This is a false optimization. The primary motivation seems to be that the OP doesn't like UserDict. Looking at the patch, I find the existing code to be more self- evidently correct and maintainable than the proposed new code. Though this is probably a matter of taste. _____________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1367711> _____________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
