Pitfall

This is an easy pitfall to make:

(function(){
var Object = Object;

})();

Object ends up undefined. So, a fix for that would be:

(function(){
Var Object = window.Object;

})();

But it is slower than this:

(function(){
var O = Object;

})();

another obvious working Pattern is

(function(Object){

})(Object);
