Nick Coghlan added the comment: The "used directly as the metaclass" is a reference to https://docs.python.org/3/reference/datamodel.html#creating-the-class-object further down, and specifically the "metaclass(name, bases, namespace, **kwds)" call. It's not saying Python has a way to bypass that instantiation process.
As a result, your code is consistently getting to that step just fine, but *that call* is throwing an exception. Hence my comment earlier that there's a case to be made that we should be better indicating where we were in the type creation process when the metaclass resolution failed. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28437> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
