Description:
------------
Attempting to access a closure through the ReflectionMethod's getClosure() method results in a fatal error declaring that a "... Call to undefined method ReflectionMethod::getClosure() ..." has occurred.

The example below was taken from the RFC described on http://wiki.php.net/rfc/closures.

I have tried this on two different Windows binaries for PHP 5.3.0 (RC3-dev and the more recent RC5-dev).

NOTE: 5.3.0RC5-dev was not available for the PHP version listed, so I chose 5.3CVS-2009-06-23 (snap) as the version I tested it on (same date as the Windows binary I downloaded from http://windows.php.net/snapshots/).


Reproduce code:
---------------
class Example {
  public $x = 4;
  function printer () { echo "Hello World: $this->x!\n"; }
}
 
$class = new ReflectionClass ('Example');
$method = $class->getMethod ('printer');
 
$object = new Example;
$closure = $method->getClosure ($object);
$closure ();
$object->x = 5;
$closure ();

Expected result:
----------------
Hello World: 4!
Hello World: 5!

Actual result:
--------------
Fatal error: Call to undefined method ReflectionMethod::getClosure()
