[issue43761] Documenting dataclass and namedtuple changes for structural pattern matching

[Eric V. Smith]

Eric V. Smith <eric at trueblade.com> added the comment:

I do think it's worth mentioning that __match_args__ is automatically generated by @dataclass (if the class doesn't already define __match_args__). That seems like behavior that's very specific to @dataclass. Where else would you find out that defining your own __match_args__ prevents @dataclass from adding it?
