(function(window,document,undefined){ ... })(this,this.document);

gistfile1.js

// everyone's new favorite closure pattern:
(function(window,document,undefined){ ... })(this,this.document);

// when minified:
(function(w,d,u){ ... })(this,this.document);

// which means all uses of window/document/undefined inside the closure 
// will be single-lettered, so big gains in minification.

// it also will speed up scope chain traversal a tiny tiny little bit.
// additionally it protects against the case where someone does `undefined = true`


// tech details:
(function(){ })() // is a self executing anonymous function
// and when we 
(function(myname){  })('paul') // we're just bypassing a var declaration at the top

// and then in this case, `this` is always the global object when in global scope so 
// we can safely use it.



// and a horribley awesome idea. duck punch to switch up the args passed in on all ready functions

(function(oReady){
    $.fn.ready = function(fn){
        return oReady.call(this, function(){ fn.call(this, $, window, document); });
    };
})($.fn.ready);
 
// which enables
$(function($,window,document,undefined){ alert(document) })
