So, at issue is attaching tracebacks to exceptions keeps too much alive and thus makes exceptions too heavy? If the traceback was passed to the exception constructor and then held as an attribute of the exception, any exception meant for "light" work (ie., not normal error flagging) could simply decided not to include the traceback, and so it would be destroyed, removing the weight from the exception. Similarly, tracebacks could have some lean() method to drop references to the frames. _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
