I think storing the traceback in the exception is a 3.0 feature, since it depends on the effective 'del e' at the end of the except clause for avoiding most cycles. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-3000 mailing list [email protected] http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
