I might be missing something, but isn't this basically covered with the enumerable flag? And that brings us back around - if we only had unique symbols and we defined the property using the symbol, and made it enumerable false, would it still be private? Am I missing something obvious (I probably am)? I know this is more work, but it would be more orthogonal. Sugar could be added to class to make this better. - Russ
