PHP: Chainable cURL Object Oriented API

In my Chainable post :

I got some requests for an example of a pratical use of the method chaining wrapper.

Remember the cURL Object Oriented API Class?

Let's combine them into a
dynamic-chainable-object-oriented-api! ;)

(new Chainable(
      new cURL("http://graph.facebook.com/CaffeinaLab")
 )) -> setopt(CURLOPT_HEADER, 0)
    -> setopt(CURLOPT_RETURNTRANSFER, 1)
    -> exec() -> _get_return($data)
    -> close()
;

print_r( json_decode( $data ) );
