Is it possible to pass user-defined parameters to the constructor of
dynamic subclass of MovieClip in AS? Basically something like this:

dynamic class class1 extends MovieClip {
  function class1 (data1, data2) {
    trace(data1);
    attachMovie(...);
    trace(data2);
  }
}

var obj:class1 = new class1(1, 2);

What I am trying to do is to create a library item (or component) that
can do things as specified. For example, a car object. At the object
creation time, we pass data such as from location and to location.
Once created, the car will move as specified. If I want two cars
moving from a to b and c to d, respectively. All I need to do in the
main stage is:

var car1:Car = new Car (a, b);
var car2:Car = new Car (c, d);

Constructor of Car (a dynamic subclass of MovieClip) will attach the
movie (car) and move it from one location to another.
