New submission from retnikt <retn...@gmail.com>:
Essentially the same as https://bugs.python.org/issue29581 (more detail is there), but for the additional meta-classes enum.EnumMeta and probably typing.NamedTupleMeta (discussion needed - is there a use-case for this?) The __new__ method on these metaclasses should include **kwargs at the end of the method definition and pass them on to the super call in order to allow the special method __init_subclass__ to be defined with custom parameters on classes using the metaclass. (also, perhaps the issue for typing should be reported separately on github python/typing instead) ---------- components: Library (Lib) messages: 354104 nosy: retnikt priority: normal severity: normal status: open title: __init_subclass__ causes TypeError when used with more standard library metaclasses (such as EnumMeta) versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38397> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
