Eric V. Smith <e...@trueblade.com> added the comment:
The problem is that dataclasses is looking for a default value for a field by looking at getattr(cls, fieldname), which returns a value when fieldname is "mro". I think the best thing to do, at least for now, is prohibit a field named "mro". Ultimately I'd like to see cls.mro go away (maybe being replaced by a builtin), but I realize that's not likely to happen. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45531> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
