That's certainly a use case that has failure modes we need to test.

I spent quite a while trying to get compile-time tests to work and there is a
lot of surgery required to make it work as expected and have the overrides
work correctly.

Even then the final solution I had was overly simplistic and didn't allow
layering of tests because the source to test mapping was quite simple.
