harmony Sets and Maps have generators now ... generators break backward compatibility because cannot be polyfilled.
How are you dealing with Set.proottype.values since you cannot shim a generator behavior? This is my question (also ... WeakMaps were extremely hard to polyfill, no generators ... Sets and Maps were easy to polyfill ... now impossible with generators). This is confusing :-/ This is what I can read here: http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets Best Regards On Thu, Jul 11, 2013 at 3:37 PM, Mark S.
