Super, not so hard

super.js

// super simply snips the current objects [[Prototype]] out of the chain. 
// It then continues to operate on the object and places that [[Prototype]] back in the chain when
// we are done.

var Base = {
  super: function(method) {
    var _proto = this.__proto__;
    var args = [].slice.call(arguments, 1);
    this.__proto__ = _proto.__proto__;
    try {
      this[method].apply(this, args); 
    } finally {
      this.__proto__ = _proto;
    }
  }
}
