@tabatkins a Map is something that has a [[MapData]] slot, that i can `Object.getOwnPropertyDescriptor(Map.prototype, 'size').get.call` and receive a meaningful answer. If these qualify, then Map's IteratorPrototype makes sense.

@domenic thanks for the correction on the history of it; it seems telling that such a thing hasn't been discussed in committee, and nobody seemed to know about it, when we discussed refactoring these builtins, since at least 2014.
