Not sure this is a good idea or not.
Motivation: we have too many fragmented traits, which are easy to forget to add in
with()attrs.Now
__str__will more looking like a normal #[pymethod]. But what it backs will be very different. It actually doesn't create a real pymethod, but actually creating slot_str. And__str__will be placed by a slot-wrapper descriptor.This can be applicable to other single-method traits too.
Pros: Easy to understand. No worry to forget to add
with()Cons: Confusing because it have different semantics comparing to other real pymethods.
