As long as the contract that `map.set(x, y); map.get(x) === y` works for any `x` and `y`, then you're probably fine.
I think it would have to subclass those methods by using toString() on
the argument passed. It seems that would still be Map-like though.
Hmm, so that invariant wouldn't hold? I assume `has` would be similarly broken? Seems… not so Map like, besides perhaps having some operations with the same name as Map's.
