I feel very strongly that, as much as possible, an Enum should Just Work. Requiring users to write their own __format__ any time they create a new mixinEnum in order to get sane default behaviour is just not cool. And while the behaviour of switching from str.__format__ to mixin.__format__ can appear a bit magical, it is nothing compared to Enum as a whole. You can review the attached patch to see what I mean about filtering the format spec to decide which __format__ method to call. Any code besides the basic width and justification codes will switch to the mix-in's __format__; so '+', 'b', '%Y', 's', and everything we haven't thought of yet will switch to mix-in. ---------- keywords: +patch stage: -> patch review Added file: http://bugs.python.org/file31310/issue18738.stoneleaf.01.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18738> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
