I feel `permutations()` would be a good addition, but the others are too special. This is opinionated, but I regard `permutations()` more as an[array creation routine](https://numpy.org/doc/stable/reference/routines.array-creation.html), rather than an algorithm....

> I agree this definitely makes sense in an external package Are we talking about `permutations()` or a broader set of combinatorial functions like [proposed above](https://github.com/numpy/numpy/issues/26206#issuecomment-2039633646)? I would be willing...

The difficulty is easy: What you need to do: 1. Set up the development environment: https://matplotlib.org/devdocs/devel/development_setup.html 2. Build the docs https://matplotlib.org/devdocs/devel/document.html and measure the build time We would like to...

Thanks @Anson0028 your measurements confirm the ~10% speedup assumption. I believe it's worth adding PyStemmer to our CI setup. Do you want to open a PR for that?

Add it to https://github.com/matplotlib/matplotlib/blob/main/requirements/doc/doc-requirements.txt I think it's also reasonable to add it to https://github.com/matplotlib/matplotlib/blob/main/environment.yml

I don't know that one can prevent building a search index. Do you know how? - This would at least be interesting for measuring how much time is left for...

Sure.

Thanks for the reminder on #16221. At least for the case of widgets, I feel that holding explicit references is simpler than the lambda construct (explicit is better than implicit).

This comes in through #25247, which aggregates all contours in one Collection rather than having a separate Collection per contour. While the old approach set one color per collection, the...
