> When instantiation fails, recheck to see the missing abstract methods had > been defined? I've written about it in the python-ideas discussion as well, and completely agree. There is no other approach that would guarantee correctness across all APIs, both internal and 3rd party. Adding a function to recalculate will require everyone to use it, and worse, know that it even exists. The overhead should be quite low as this case is probably rare and the recalculation can happen only on failure. I'm not sure however, what are the implications of changing Py_TPFLAGS_IS_ABSTRACT during type creation. ---------- nosy: +bar.harel _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41905> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
