To demonstrate how to wrap a global javascript function, which returns  
something into a class in a typesafe way.
So:

--- JS library ---
function add(x,y){ return x+y; }

-- haxe wrapper --
class AddClass {
   static function __init__() { AddClass.prototype.add = untyped  
__js__("add");

   public function add(x:Int,y:Int):Int {return null;}
   // if I don't return null, haXe compiler will complain

   public function new();
}

new AddClass().add(1,2); // 3




Kind regards,
