Yeah, its funny how such a language construct actually is implemented in 
Firefox without the world knowing. Chrome/Opera and IE have nothing alike.
However: It will not become standard before the release of IE10 and 
therefore will take - estimate at least more 5 years
until it can be safely used in the JavaScript context - rough estimate.

class MyButton extends Sprite {
    public function MyButton() {
      addEventListener(MouseEvent.MOUSE_OVER, handleMouseOver);

This is a very simple and common case of a event that is not possible to 
be fixed without weak listeners.
