(Resolved) Prototype-based delegation from function constructed object to class instance

[brendan]

Kris Zyp raised this on es4-discuss. Given

class C {
  var x : int = 42;
  function C(x) : x = x {}
  public function m():int x
}
c = new C;
function F() {}
F.prototype = c;
f = new F;

Right now, setting f.x = 33 sets c.x, and the type constraint is enforced. This is a bug: there should be an expando shadowing c.x created in the Object instance f that was created by new F.

Need Proposal or Spec language, then RefImpl? fixing -- or perhaps the latter if we have the former, but it's not clear to me that we have a spec requiring this yet.

Simple spec/refimpl issue IMO, the behavior here should just follow from standard ES3 rules, no?
