Would it make any sense to add an opt-in option to emit a warning when a new type is created with Py_TPFLAGS_HAVE_GC but it doesn't implement tp_traverse? Maybe also emit a warning if it doesn't implement tp_clear? Maybe it could be a ResourceWarning emitted in development mode, when -X dev is used on the command line. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38006> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
