These case rewrites are... odd. I don't see how it's better in any way. Is there a setting of some sort that's causing this? Maybe because one case has a guard... but that doesn't seem like a good enough reason to indent every case and wrap them in parens.

this is https://astral.sh/blog/ruff-v0.9.0#automatically-parenthesized-if-guards-in-match-case-statements (which Black doesn't do)

This case (237-245) doesn't have an if-guard, though. Are all cases put in brackets if any have a guard?

in that case it might just be due to the line length being shorter than it was previously? Addressing #133123 (review) might fix it

I’m not sure that’s the issue. This uses more horizontal space than not wrapping in parens, due to the additional indent.

I suspect it is because one of the cases has a guard, which feels like a bug.

I kept the wrap-to-80 commit separate (42ce014 (#133123)), and the change was before that.

Or maybe it has to do with the name assignment to hole?

Yep, it seems to be as hole that triggers the brackets. That does seem like a bug?

Yes. It's not just class patterns, outer grouping symbols in the pattern like (), [], and {} aren't being used effectively. See this playground, where I have my expected formatting going in and the buggy formatting coming out: https://play.ruff.rs/81f62f2d-6858-43eb-8a9b-67dcebdc56f6?secondary=Format
