Create object without instance name

Question

hi
here is the problem , i have hero shoot bullets and because of that i cant give the objects an instance names and i wanna check if the object on the stage or not and that is easy when
i do    var bullet:BULLET = new BULLET
if (bullet.stage){
addChild(bullet)
but the problem that when i do like this
addChild(new BULLET())
i know that , flash give them a names but how can i check their names??
if(???.stage)
thank you

Per Ned's suggestion you should use some structure. Because it seems you will use animations of large numbers of objects - Vector is the best because it is faster than Array.
Here is an example in two iterations - first as timeline code (just paste it on timeline), and below - as document class - you can use it by placing it into the same directory as your fla and assign doc class to Shooter:
import flash.display.Sprite;
import flash.events.Event;
var bullets:Vector.<BULLET>;
init();
function init():void
    makeBullets();
    placeBullets();
    shoot();
function shoot():void
    addEventListener(Event.ENTER_FRAME, moveBullets);
function moveBullets(e:Event):void
    for each (var b:BULLET in bullets)
        b.x += 10;
function placeBullets():void
    var nextX:Number = 0;
    for each (var b:BULLET in bullets)
        addChild(b);
        b.y = stage.stageHeight * .5;
        b.x = nextX;
        nextX -= b.width * 2;
function makeBullets():void
    var numBullets:int = 500;
    bullets = new Vector.<BULLET>();
    while (numBullets--)
        bullets.push(new BULLET());
Class:
package
    import flash.display.Sprite;
    import flash.events.Event;
    public class Shooter extends Sprite
        private var bullets:Vector.<BULLET>;
        public function Shooter()
            init();
        private function init():void
            makeBullets();
            placeBullets();
            shoot();
        private function shoot():void
            addEventListener(Event.ENTER_FRAME, moveBullets);
        private function moveBullets(e:Event):void
            for each(var b:BULLET in bullets) {
                b.x += 10;
        private function placeBullets():void
            var nextX:Number = 0;
            for each(var b:BULLET in bullets) {
                addChild(b);
                b.y = stage.stageHeight * .5;
                b.x = nextX;
                nextX -= b.width * 2;
        private function makeBullets():void
            var numBullets:int = 500;
            bullets = new Vector.<BULLET>();
            while (numBullets--) {
                bullets.push(new BULLET());
