Sorry for the delay, here's what I came up with.

I added a FIXME about the recursion-breaker which I have a feeling might
not work.

There's also some stylistic problems with the tests:

- We shouldn't test the return value of `cl-deftype`: I don't think it's
  documented anywhere and I don't think it's good practice to pay
  attention to the return value of declarations.
- They use `eval` too much.
