Note: Implementing a metaclass in Python is hard, it's easy to mess up with closures: see bpo-29270 "ctypes: fail to create a _ctypes._SimpleCData subclass using a closure like calling super() without arguments". type.__new__() is called twice on the same type dict, and the second call overrides the __classcell__ cell value. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47143> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
