The doctest failure is unrelated, here's a PR to fix it: #104852

[vstinner]

@AlexWaygood: Why did you merged the branch 'main' into remove_pipes? I created this PR 49 minutes ago. Do you expect regressions since main changed in the meanwhile? I was awaiting CI tests to complete, and with this merge I have to wait 30 minutes again :-(

[hugovk]

I expect it's to include the doctest fix #104852 from main, so we can get a nice clean (green) slate here.

[AlexWaygood]

@vstinner sorry if I was unhelpful. The doctest CI check was failing on this PR for an unrelated reason; after Hugo merged his fix for the doctest failure into main, I thought I could retrigger the check for you here by merging main into this PR branch. But, since it wasn't a "required" check, you probably could have merged the PR anyway, despite the CI check being red. My bad — sorry again :-)

[hugovk]

By the way, we've now made available GitHub's "Enable auto-merge" feature for this repo, so this could be a good opportunity to give it a spin:

Oh, I didn't see. In that case, thank you :-) I was just surprised to see a merge without any explanation.

Apologies — I'll explain my actions next time 😄
