Poor choice of words. The concrete implementations didn't change at all. Perhaps the concrete implementation need to be brought more in-sync with the ABC. That would be reasonable; afteralll the goal is substitutability -- that is the only reason that the old xrange morphed into something with nearly useless count() and index() methods in the first place. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28197> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
