is it possible to put Class in a variable and access the class's static variables and functions in actionscript3?

Question

Say I had the following class

public class Scene{ 
  public static var title="new scene";
  public function Scene(){}
  public static function start() { trace("scene started"); }
}

How can you access the Scene class's static variables and functions like this?

var i:Class = Scene;
trace(i.title);
i.start();

I'm trying to figure out how variables assigned with Class work in actionscript. Any tips would be welcome. Thanks.

Static methods are called from the class:

trace(Scene.title);
Scene.start();

Singleton patterns enable constructor, local reference, and potentially abstraction through interface classes.

Example of Scene as a singleton:

package
{

    public class Scene
    {

        private static var instance:Scene = new Scene();

        public static function getInstance():Scene
        {
            return instance;
        }

        public var title:String = "new scene";

        public function Scene()
        {
            if (instance)
                throw new Error("Scene is a singleton and can only be accessed through Scene.getInstance()");
        }

        public function start():void
        {
            trace("scene started.");
        }

    }
}

Your example implementation would now be:

var i:Scene = Scene.getInstance();
trace(i.title);
i.start();
