+   and the easiest way is to have different hashers for different
+   types.
+
+   Known differences from the ES6 specification:
+   - Map is a Lang.Class, not a ES6 class, so inheritance,
+     prototype, sealing, etc. work differently.
+   - items(), keys() and values() don't return iterators,
+     they return actual arrays, so they incur a full copy everytime
+     they're called, and they don't see changes if you mutate
+     the table while iterating
+     (admittedly, the ES6 spec is a bit unclear on this, and
