Agree we want both. Provided the right class instance (Map for 
MapIterator) is created, the iterable prototype methods seem just as 
generic. This really wants something hard (not impossible, just 
undertested) to add: Iterable.prototype or an unnamed 
%IterablePrototype% above Array.prototype, Map.prototype, Set.prototype, 
etc. Someone please raise on es-discuss, if this seems right.
