[haXe] best strategy to port an existing js library

[Ian]

wow. that wasn't at all what I was thinking, but I prefer this.  you 
lose type checking, but you eliminate the wrapper.  my thought was:

// js library (same)
function niceAlert(txt) {
  alert("### " + txt + " ###");
}

// js wrapper
function JsWrapper() {
  this.callNiceAlert = niceAlert;
}

// haxe code
extern class JsWrapper {
    public function new():Void;
    public function callNiceAlert():Void;
}
class Main
{
    public static function main() {
      var wrapper = new JsWrapper();
      wrapper.callNiceAlert("hello to you");
    }
}
