Description:
------------
The RecursiveArrayIterator class does not implement Countable interface, although it extends ArrayIterator.



Test script:
---------------
$it  = new \ArrayIterator(array(1, 2, 3));
$rit = new \RecursiveArrayIterator($it);

var_dump($it instanceof \Countable);
var_dump($rit instanceof \Countable);

Expected result:
----------------
bool(true)
bool(true)

Actual result:
--------------
bool(true)
bool(false)

Reproduced on 5.4.1. The problem is probably that ArrayIterator implements Countable only *after* RecursiveArrayIterator already inherited from it (see http://lxr.php.net/xref/PHP_TRUNK/ext/spl/spl_array.c#1978). Fixing should be as simple as moving that macro a few lines up :)
