@DeinAlptraum Can you merge `main` into this branch? I'd like to merge this with a green CI.

@tbaederr CI for this patch has failed due to unrelated failure that is likely to be connected to your work:

This is the second time during the past 7 days that I see `AST/Interp` tests failing in unrelated PR. Can you make sure pre-commit CI is green before you land your commits? You can open PR, and merge them as long as CI is green. Both Linux and Windows pre-commit CI has enough capacity these days, so it shouldn't introduce too much latency into your workflow.
