Adding a MovieClip to the Stage from a Class function

Of course, it’s easy enough to do when not working with classes. Basically, I want to be able to execute a function from one of my classes that does the following -

function buildArea():void
{
    var i:Number = 1;
    this[ "tile_" + i ] = new TileSet01(); // a for-loop will be used later, so this is necessary
    addChild( this[ "tile_" + i ] );
}

buildArea();

If I remember correctly, I did this in AS2 using Delegates. Unfortunately, it doesn’t seem to work the same way in AS3…
