Improving Function.prototype.bind

[Andrea Giammarchi]

just to make it more concrete for those interested:

IDL Like description and code ... to me this is a much faster/easier/better
solution than Function#bind ... unshimmable for IE < 9 but ... you know,
some wrapper could do the trick in any case.

/**
 *  interface ObjectHandler implements EventListener {
 *      void                handleEvent(in Event evt);
 *      void                remitEvent(in Event evt);
 *      attribute   Object  events;
 *  };
 *
 *  @link
http://www.w3.org/TR/DOM-Level-2-Events/events.html#Events-EventListener
 */
var ObjectHandler = {
  handleEvent: function handleEvent(e) {
    var
      events = this.events,
      type = e.type
    ;
    if (events.hasOwnProperty(type)) {
      events[type].call(this, e);
    }
  },
  remitEvent: function cancelEvent(e) {
    e.currentTarget.removeEventListener(
      e.type, this, e.eventPhase === e.CAPTURING_PHASE
    );
  }
};

Best Regards
