Can you update this docstring to mention M? I don't know the non-lean way to write the terminology, but persumably you want to talk about the lie module bracket or similar.

It looks like you didn't touch this docstring? Given the 👍 I assume that wasn't deliberate? If it was, feel free to re-merge.

Argh, apologies I missed this and confused myself into thinking your original remark referred to the module doc string.

Unfortunately this has now landed in master. Maybe the best thing to do is for me to include an update to this doc string as part of my next PR in a day or so.

It's almost as if you intended this generalization from the beginning, given how easy the fixes were!

I had not intended it and I was surprised myself!

This seems to have been cancelled by a bot; I'm guessing this was because I sent it to bors while it was still building (bors was empty and I had just updated a doc string).

I will thus try again.
