I have no opinion on PEP 380 specifically, but surely a *sufficiently* desirable goal *should* be a reason for breaking the rules? Obedience to some abstract rule just because it is the rule is not a virtue. The moratorium is there to advance Python as a whole, and if (a big "if") it becomes a hindrance instead, then Guido should make an exception. I promise that I won't cease taking his pronouncements seriously if he does :) -- Steven D'Aprano _______________________________________________ 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
