Iterate through a for loop leaving one index out

1

I often need to set the alpha of all but one of a list of objects.

     
beastie1.alpha = 0;
beastie2.alpha = 1;
beastie3.alpha = 0;
beastie4.alpha = 0;

I am wondering what is the best way to do this with a for loop?

private var beastieArray:Array = new Array(beastie1,beastie2,beastie3,beastie4);

for (var i:int = 0; i < beastieArray.length; i++) 
  {
   beastieArray*.alpha = 0;
  }

This loop obviously sets all of the objects in beastieArray to alpha = 0. is there a way to leave one index out of the loop?

Thanks!
