ActionScript 3 :: Define Variable From Its Creator On Stage

I am trying to split up my code in classes. But there is a issue what really bothers me. When I create a class for functions I am giving its own stage. Like this:
dragf:Dragfunctions = new Dragfunctions(this)

And in the class i use this
var stage:Object;
public function Dragfunctions(stage:Object) {
this.stage = stage;
}

As you can see I can now call a variable of the stage using stage.var1 = "hi" but when I need to adjust that variable many times it gets a quite messy. There is a way to tell that when I call var1 he knows i mean stage.var1 without need to call stage.

Its:
var var1 = stage.var1
And then using
stage.var1 = var1
But that is quite unhandy too is there a better way?
