Loading Library items via an Array

I used to put a load of instance names linking to library objs into an array in AS2, then use a loop to add them to the stage…

I htought this would work in AS3, alas no.

var list:Array new Array("one", "two","three");
for(var i:int=0;i<list.length;i++)
  this["emptyClip"+i] = new MovieClip();
  this["emptyClip"+i].x = i*50;

“one”,“two” etc are the names of the images in the library … //:block:

It’s hard to find out the new ways of approaching the old AS2 methods … Thanks for any help
