Running collection of IIFE Patterns

iife.js

(function( window, document, undefined ){

})( this, this.document );

(function( global, undefined ){

})( this );


// miketaylr
(function( win, doc ){

  // SCREW U UNDEFINED    

})( window, document );


// ralphholzmann
(function poll() {
  
  /* Lots of stuffs here */
  if ( cssIsReady ) {
    cssCallback();
  } else {
    setTimeout( poll, 50 );
  }

})();


// mennovanslooten
new function() {

  // No arguments though

}


// addyosmani
(function(){ 
  
  arguments.callee(); 

}());

(function(){
 
  /* do stuff */

}());



// rmurphey
!function(){ 

  // Note that I don't like this one, but it does exist :)

}();

I like:

(function(win,doc){

})(window,document)

SCREW U UNDEFINED

I enjoy recursive IIFEs, we use them to poll for css callbacks in yepnope.js

(function poll() {
  /* Lots of stuffs here */
  if ( cssIsReady ) {
    cssCallback();
  } else {
    setTimeout( poll, 50 );
  }
})();

Not sure if this is technically an IIFE because of the "poll" identifier, but it beats using arguments.callee.

<3z

new function() {
    // No arguments though
}

Including just because it technically counts, even if ralph's kicks its ass a little ; )

(function(){
arguments.callee();
}());

and I guess this is one of the more common immediately invoked variations I use:
(function(){
/* do stuff */
}());

No funky syntax highlighting. I'm commenting from a phone and Im lazy.

!function(){ /* ... */ }()

Note that I don't like this one, but it does exist :)

Here are some more:

null,function(){ /* ... */ }()

this,function(){ /* ... */ }()

666,function(){ /* ... */ }()

'☹',function(){ /* ... */ }()

-function(){ /* ... */ }()

+function(){ /* ... */ }()

|function(){ /* ... */ }()

^function(){ /* ... */ }()

>>>function(){ /* ... */ }()

~function(){ /* ... */ }()

-([[{}||{}]])>>>function(){ /* ... */ }()

None of them should be used though.
