Dataclasses should define __replace__ in 3.13 #17471
Description
Feature
Add __replace__ on dataclasses in 3.13+.
Pitch
Similar to how we're special casing support for __replace__ on namedtuple, we should do the same for dataclasses.
This is causing some false positive issues in TypeShed, where __replace__ isn't getting registered on dataclasses (FunctionProfile and StatsProfile) and is needed to properly support the protocol for copy.replace: python/typeshed#12262
Activity
Add `__replace__` for dataclasses in 3.13 (python#17469)
