using the WITH keyword in ActionScript AS3

var retVal:stuff = new stuff();
with(retVal)
{
    a = 1;
    b = 2;
    c = 3;
}

trace("retVal.a == " + retVal.a);
trace("retVal.b == " + retVal.b);
trace("retVal.c == " + retVal.c);


internal class stuff
{
    public var a:int;
    public var b:int;
    public var c:int;
    public function stuff():void{}
}

//output:
/*
retVal.a == 1
retVal.b == 2
retVal.c == 3
*/

Not sure I find this useful. Saves typing, but I am not sure how I feel about debugging code written like this. Also, intellisense in flashDevelop doesn't appreciate it. Maybe I will use the with keyword... Depends on how much typing I need to save and what makes things more readable.
