Kenta.Function.invoke.js

Function.implement('Invoke', 
   function(args){
      var tmp = Class.instantiate(this);
      var init = this.prototype.initialize;
      if(init){
         init.apply(tmp,$splat(args));
      }
      return tmp;
});

with this little modification if a single element is passed throught it $splat that into an Array :)
