It would be useful to be able to form the intersection and the union of two Sets. These are natural operations that are currently not part of the API (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets).
Similar methods would make sense for Map, but one would have to think about what to do in the case where the key but not the value matches. An intersection is equivalent to a particular filter, so an alternative might be to add a method like Array.filter to Sets instead. (I filed bug 847355 for this and was told this mailing list was the right place for this suggestion.) -- http://www.fastmail.fm - Send your email first class _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
