See my more recent message for an elaboration of that, but I don't
think we disagree.

Not in ES4, though you can use different namespaces of course:

  class C {
    function get x() private::x
    function set x(v) private::x = toInt32(v)
    private var x = 0
  }

The catchall mechanism has to deal with these issues and have a
way of asking for default behavior to be invoked.  I'll have more
to say about this next week.
