class MyDelegate {
	public static function create(o:Object, f:Function):Function {
		var arg:Array = arguments.slice(2);
		var newF:Function = function ():Void {
			f.apply(o, arg);

}

PS: return добавил

class MyDelegate {
	public static function create(o:Object, f:Function):Function {
		var arg = arguments.slice(2);
		var newF = function () {
			return f.apply(o, arg);
		};
		return newF;
	}
}
