title: Method chaining with function arguments
body: <p>What's the best way to chain methods in CoffeeScript? For example, if I have this JavaScript how could I write it in CoffeeScript?</p>
  
  <pre><code>var req = $.get('foo.htm')
    .success(function( response ){
      // do something
      // ...
    })
    .error(function(){
      // do something
      // ...
    });
  </code></pre>
