I'd love to have a full set of collections for JavaScript, but just to clarify, adding a
separate OrderedObject wouldn't address most of the issues I've raised:
1. it would be no help to JSON - there would still be the severe expressiveness and object
allocation overhead I previously described
2. it would remain a surprising "gotcha" that numeric indices behave specially
on Object
3. it would not address the backcompat issue with all the sites that depend on
ordering

Another idea might be to introduce OrderedObject or somesuch with guaranteed
enumeration order.
You might lose object literal support (although that could be readded), but
that's the only
loss that comes to mind after brief thought.
