[issue33141] descriptor __set_name__ feature broken for dataclass descriptor fields

[Eric V. Smith]

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

Nick Coghlan suggested (on python-dev) to have Field implement __set_name__ and call through to the default value, if it exists.

That approach seems to work fine. I'll generate a PR with tests sometime before today's release.
