> Thanks, done. https://github.com/tc39/ecma262/pull/13 This seems less useful than adding `%IteratorPrototype%.map` and `%IteratorPrototype.filter`. It also clarifies some of the confusion about whether you are changing the values, keys, or entries (since you would need to specify explicitly). Unless I'm missing something (quite possible!), I would prefer not to add new methods to Map and Set when they could be added to `%IteratorPrototype%`.
