Looks good overall. As with the last pr, I don’t think anything more is gained from me staring at this for any longer. Most of the comments here are just minor things, and I think we can merge after those are addressed.

One thing to note though: Do we have any tests for C? I don’t see any in this pr, but maybe I’m just being blind.
