Weak references are on the horizon for JS:

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.
Not all listeners have to be weak references.
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.
