It turns out that this bug reproduces with any subclass of the generic type with a weakref slot, even without any multiple inheritance going on. For example: class Invertible2(Invertible[KT1, KT2]): pass is enough to trigger this bug along with the Invertible class in my previous example. Attaching the more minimal repro with this comment, and renaming the issue to remove the reference to multiple inheritance. ---------- title: Class with __weakref__ slot cannot inherit from multiple typing.Generic classes -> Class with __weakref__ slot cannot inherit from typing.Generic subclass Added file: https://bugs.python.org/file49353/bpo41451-repro.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41451> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
