I still have no idea what your problem with this is. Your objections aren't making any sense. In general, generators are very hard to polyfill. (Not impossible, as you can do a CPS transform of the source code, but very difficult.) This is not the general case, this is a very simple specific case. You just need a trivial little iterator that runs over the internal data structure of the Map/Set. I've written these kinds of things tons of times for classes in PHP, so they can work conveniently with PHP foreach() loops. That said, the reason the harmony page defined the methods with generators is that, as easy as it is to write an iterator manually for them, it's *even easier* to write them with a generator. That's all. ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
