That's the case I care most about. > I cannot get pickle failure on those same classes; I suppose you mean "if you create the same enums using class syntax"?

I'm not 100% sure I know what "that" refers to here. -- --Guido van Rossum (python.org/~guido) _______________________________________________ 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
