While this was a pain to get working, that pain only went to prove the value of using proper "types" (even if only an enum) for different expression types: just finding all the places to edit was a chore, and easy to make mistakes (forgetting bits here and there). Strangely enough, this exposed a pile of *type* aliasing bugs (next commit).
