This PR is now in a state where the core seems to work. At the same time the tests are inadequate and this PR also introduces a lot of duplication. Together, this makes it hard to be confident about this change working well for more than the most basic cases.

Alright, I've left some comments. I think it looks good. We can clean it up and have a second pass. 👍
