I suspect compiling to something like this would solve the problem? Notice that here I'm passing A to the anonymous function as the __super__ parameter instead of directly referencing it from the outer scope.

this.A = (function(__super__) {
  __extends(A, __super__);

  function A() {
    A.__super__.constructor.apply(this, arguments);
  }

  return A;

})(A);

@erisdiscord: exactly what I was thinking.

Ditto.

$ coco -bpe '@A = class extends A then'
this.A = (function(superclass){
  A.displayName = 'A';
  var prototype = __extends(A, superclass).prototype, constructor = A;
  function A(){}
  return A;
}(A));
...

Thanks -- fixed using coco's trick in the patch above.
