Test Plan:

[djava]

BTW I would prefer that if you make a change related to one of my comments, just respond with the hash of the commit that fixes it and don't resolve - i'll either resolve or suggest a different fix

And feel free to argue and stuff if you disagree as well, that's the point of all this

I'd like to see some more tests before this merges, I think. In particular, I think that the multiple-errors case is probably where most of the snags lie, and the tests don't currently cover that.

Yea that's next on the to-do list, along with better docs and formatting

I'm marking this as ready for review. I wasn't able to implement all the features I've planned to (notably std::format support), but what we have right now is enough to get started with other tasks.

Everyone is busy, all the tests passed, and the design has been debated to death. So this is getting merged
