Add new methods to MovieClip class?

programming flash
1

Hi!

Is there any way to add methods to the existing MovieClip class so that later I can use them everytime I instantiate a MovieClip? Something like this:



package {
    import flash.display.MovieClip;
    public class myClass extends MovieClip {
       public function myMethod() {
         //do stuff
       }
   }
}

Then, without instantiating myClass, I want to be able to call that method like this:



var newMc:MovieClip = new MovieClip();
newMc.myMethod();

Is it possible?
