forEach / map is not a function #451

This one I feel is bordering on help/feature request than an issue, so apologies in advance..

If I pass an iterable into the JS world (in my case, an instance of a class that extends ArrayIterator) then attempting to get forEach or map functions on it throws an error

TypeError: users.forEach is not a function

meaning that i can't have an interoperable lazy loader that works with the same JS code.

Is this actually do-able? I appreciate i can process and pass the items as a 'true' array, but these are database records and could be plentiful. If there are any hooks / magic methods / tricks that can be used to fool V8 into allowing this to work, that'd be awesome.

Oh, nice catch that the ES6 features are still missing.

And yes, this should be do-able. I haven't (yet) tried whether it'd be even possible to simply reuse the implementations on Array.prototype
