Можно сделать посимпатичнее:

public function Test()
{
	callMethod(trace3Args, "1", "2", "3", "4", "5");
}
 
private function callMethod(method:Function, ...args):void
{
	args.length = method.length;
	method.apply(null, args);
}
 
private function trace3Args(arg1:String, arg2:String, arg3:String):void
{
	trace(arg1, arg2, arg3);
}
