4033a1b33d Prove most of commutativity by relying on in-dec.
The "no" case still needs to be dismissed, but that can probably
be done by some lemma about keys in maps.

c50195942d Start moving away from purely list-based maps.
The eventual goal is to make a map be a list and a proof
that all the keys are unique.
