Actually, I think having a ready and working algorithm draft on github gist will help discussing this faster and in realistic time frames (I've should've done before starting this thread; otherwise, these are "too abstract time-stoppers" for me -- unless you know specific big issues that will be hard to implement). > > >> for adding suitable parallels from Array.prototype, but it may be worth >> recalling what developers did last time there were obvious "gaps" in what a >> native prototype provided.

I think very likely `Map#map`, and `Map#filter` will be added manually if not in ES6. Dmitry
