[AS3] Dynamic create items with for loop

Well, i have this line of code

var t1:thumbBack = addChild(new thumbBack(x, y));

And i want to create many thumbBacks with names t1, t2, t3… with a for loop. Is this possible?

I tried something like this, but it doesnt seem to work


for(i=0; i<8; i++){
    var this["t"+i]:thumbBack = addChild(new thumbBack(10 + i*200 , y));
}

Any other ideas?
