I have a piece of actionscript code I'd like to clean up, it currently looks like this:
var bm1_loader:Loader = new Loader();
bm1_loader.contentLoaderInfo.addEventListener( Event.INIT,
function (e:Event)
{
	bm1 = Bitmap(bm1_loader.content).bitmapData;
	bitmapLoadSuccess();
});
bm1_loader.load(new URLRequest("assets/img/bm1.png"));
var bm2_loader:Loader = new Loader();
bm2_loader.contentLoaderInfo.addEventListener( Event.INIT,
function (e:Event)
{
	bm2 = Bitmap(bm2_loader.content).bitmapData;
	bitmapLoadSuccess();
});
bm2_loader.load(new URLRequest("assets/img/bm2.png"));
var bm3_loader:Loader = new Loader();
bm3_loader.contentLoaderInfo.addEventListener( Event.INIT,
function (e:Event)
{
	bm3 = Bitmap(bm3_loader.content).bitmapData;
	bitmapLoadSuccess();
});
bm3_loader.load(new URLRequest("assets/img/bm3.png"));

the bitmapLoadSuccess just updates the loading screen, so I'm just looking for a way to perhaps reduce this to:
bm1 = loadBMP("assets/img/bm1.png");
bm2 = loadBMP("assets/img/bm2.png");
bm3 = loadBMP("assets/img/bm3.png");
while having a magic loadBMP function that does the above, but my problem is, without passing by reference there's no way to dynamically set the bitmap to load, and because the load event is in an anonymous function I can't return it, so is there an optimal way of doing this? EDIT:forgot to add I tried this, and it does not work:
protected function loadBitmap(bitmap:BitmapData,path:String):BitmapData
{
	var loader:Loader = new Loader();
	loader.contentLoaderInfo.addEventListener( Event.INIT,
	function (e:Event)
	{
		bitmap = Bitmap(loader.content).bitmapData;
		bitmapLoadSuccess();
	});
	loader.load(new URLRequest(path));
	return bitmap;
}
