Instance-related stuff dealing with the interface will continue to work as expected and be fully backwards-compatible (unless someone complains about now having a proper __unicode__ method, in which case it will definitely go in one ear and out the other for me). -Brett _______________________________________________ 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
