In the proposal, iterators for Set are listed as todo. If engine implementers have decided to start moving forward implementing Sets, then it would be great if they could get iteration going sooner than later.
http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets Looking at the Array iterators... It doesn't seem very difficult to specify "forEach" as a proposal sketch. It just has to do the following, doesn't it? var s = new Set(); s.add('alpha'); s.add('beta'); s.forEach(function(element){}); "reduce", "every", and "some" seem similarly easy. "reduceRight" is unnecessary as a set has no order. "filter" and "map" are similarly easy but would return set objects.
