@Raymond yeah I've been thinking about this some more, and there's no way to have a "top level" method with the dataclass decorator. I think I will make a case to have a class version of dataclasses that works with inheritance. Class versions of dataclasses are used in some places like here: https://github.com/google/flax/blob/main/flax/struct.py#L184 They just call dataclass on the class in __init_subclass__. If we had something like this in the standard library, then you could put your empty __post_init__ in that class. You could also make __init__ call super so that mixins would be initialized (right now the collider pattern you showed also breaks if B is not a dataclass, and has a non-trivial __init__). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46757> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
