I’ve been browsing lots of forums lately regarding the issues involved with passing parameters into functions called by event listeners. I think I may have come up with a good solution using anonymous functions but I’m not sure yet if its “safe” to do.

```auto
this.addEventListener(Event.ENTER_FRAME, function(e:Event):void {
       myFunction(e, arguments.callee, "hello")
});

public function myFunction(e:Event, fct:Function, string:String) {
       e.currentTarget.removeEventListener(e.type,fct);
       trace(string);
}

```

The code prints “hello” once, which is what I wanted. I believe I have deleted the anonymous function, but I need some thoughts from those who may be more knowledgeable about flash garbage collection and such to be sure.
