Yes *please* to all of these. I've added most of them manually to Set.prototype on some of my projects. One additional request in a related vein - Set.prototype.chain - like .map, but the callback's value is iterated and added to the result set. (We need to coordinate this with an identical method on Array; .chain just seems to be one of the more common names for this operation in JS-land.) I use this a *lot* to, for example, expand items into related terms. ~TJ _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
