valustack is a static list in C (it's not a Python list at all) that's stored on the frame. You can't do it that way. gc.get_referrers returns you only python objects (and in fact should return you only python objects that are accessible otherwise, but those details are really implementation-dependent) _______________________________________________ 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
