So we'll update the spec to say you can't use a dict that has the default set. It's not reasonable to expect that language changes might not require updates to a PEP. Certainly, we don't have to worry about being backward compatible when it's only Python 2.5 that's affected by the change. :) _______________________________________________ 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
