I've converted some project which uses cattrs from attrs to dataclasses, but that failed because the union dismbiguator doesn't support dataclasses yet (#426 (comment)). So I used the opportunity to convert the code to the new tagged union strategy which is much nicer than the disambiguation stuff anyway. One case looks like the test added in this PR, which failed too (cattrs v23.1.2). Looking into it I saw that the problem has been fixed in main by commit b25a258. So I'm awaiting a new release, but in the meantime thought this regression test might be helpful.
