They don't, actually. They are all run with the evaluator. See
609edba7eaa2bb30df90a09541a48d97ab4a3bf8. We should probably enable it
again now.

Uf, 30 minutes. Way too long, eh. I agree it's worth it but that we need
to profile things and see what improvements we can get. Also, we could
focus on compiler improvements that would help the evaluator -- computed
goto might be a good one, so that our memoized-expression-case could
compile to something that looks more like the compilation of `case'.

Peace,
