It seems totally analogous to getting both "for x in list" and "for x, y in list_of_couples" to DTRT. (To me, anyway.) You'd still be stuck on itervalues(), but at least you'd have the option of "for _, v in d" (ie, the usual idiom for a value you're going to ignore) without creating a list. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
