interface IDrawable {}
class DisplayObject {
  public function new(drawable: IDrawable){}
}

// Different drawable items
class Bitmap implements IDrawable {}
class Graphics implements IDrawable {}
class Movie implements IDrawable {}

// So you can do the following
var graphics = new Graphics();
graphics.drawCiricle(0, 0, 50, 50);

var disp0 = new DisplayObject(graphics);
disp0.x = 100;

var disp1 = new DisplayObject(graphics);
disp1.x = 200;

var disp2 = new DisplayObject(graphics);
disp2.x = 100;

// Then doing the following will update all 3 display objects.
graphics.drawRect(50, 50, 50, 50);

// Immutable graphics
var graphics = new ImmutableGraphics();
graphics = graphics.drawCircle(0, 0, 50, 50);

var disp0 = new DisplayObject(graphics);
var disp1 = new DisplayObject(graphics);
var disp2 = new DisplayObject(graphics);

// This doesn't do anything as the graphics are immutable.
graphics.drawRect(50, 50, 50, 50);
