It should be possible to initialize a collection via another collection (right?). I prefer copy-constructors to clone() methods. That would be fine with me, if supported. Isn't it already specced to work, for Set at least, since it accepts any iterable? let copy = new Set(original); I don't recall offhand if Map accepts an iterable of [key, val] pairs, but if it doesn't yet, maybe this provides an argument that it should.
