I updated PR 18738 to document the incompatible change in What's New In Python 3.9. Sadly, I expect that almost no third-party extension module implement the PEP 489 yet. So I expect that little or no third-party code is impacted in pratice. > the module slots are then only needed if the module state actually gets > populated, so we can safely skip them if it never even gets allocated That's also my understanding. > custom module subclasses should clean up like any other class instance That sounds like a reasonable compromise to me. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39824> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
