Rationale for Dict?

Playing devil’s advocate: Is Dict really necessary? Whenever performance doesn’t matter (as much), I’d advocate Map. Otherwise, I’d expect programmers who want the extra speed to be comfortable with Object.create(null).

Assumptions about Dict:
- You still can’t use the key '__proto__'.
- You can’t invoke any methods on it.

How will it implement the iteration protocol?
