closure utils

This simple plugin adds 2 methods to jQuery for creating callbacks and providing closure over method arguments.

It is designed to help prevent code that implicitly creates closures from causing memory leaks.

var unrelated1 = 'big string';
var unrelated2 = 'other big string';
jQuery('#id').click(function() {
  self.myEventHandler();
});

can be replaced by the following, which creates a smaller closure

jQuery('#theId').click(
  $.callback(this, this.myEventHandler)
);

here is the code
jquery.closure-min.js
jquery.closure.js
pretty simple eh? This trick allows you to write OO code and encapsulate evenHandler functions in Objects, instead of ever growing closures.
It helps to avoid code like this.

                 )};
              )};
           )};
        )};
     )};
   )};
)};

jQuery have added the $.proxy() method which is similar to $.closure() and part of the standard jQuery library so should be used in preference.
This plugin is still useful for existing code and the $.closeArgs() method which has not been implemented in jQuery (yet).
