This makes hello world compile! Ignore the first commit, that's just #107146 which is waiting on merge.

I'll leave some comments inline about design choices that might be debatable.

this impl looks correct but I didn't check that it perfectly matches the existing one. Will just get test failures if there are differences cause I don't think this is unsound.
