Description:
------------
WeakRef Vesion: 0.2.6
Configure line: --with-pdo-mysql --enable-mbstring --with-openssl

The documentation states that the ::key() method returns an object.
However in my test script it returns an integer.

Also in a foreach loop the key is just an integer, never the object. I also couldn't find any other way to get the objects back out of the WeakMap.

PS: Thanks for the great extension and the support!

Test script:
---------------
$o = new stdClass();

$wm = new WeakMap();
$wm[$o] = 'foo';

$wm->rewind();

// outputs int(1) instead of the expected object
var_dump($wm->key());

Expected result:
----------------
Dump of the object $o

Actual result:
--------------
int(1)
