Ah, it seems that foreach can't handle anything non-scalar as a key.
What a pity. 

I think this should be changed in the future, because it limits the use
of Iterators. For instance, I can't use something like: 

<?php
class MapObjectData extends SplObjectStorage
{
        public function key ()
        {
                return parent::current ();
        }
        
        public function current ()
        {
                return parent::getInfo ();
        }
}
$spl = new MapObjectData ();
$spl[new StdClass ()] = 'a';
$spl[new StdClass ()] = 'b';
foreach ($spl as $object => $data)
{
        var_dump ($object, $data);
}
?>

Description:
------------
Iteration over SplObjectStorage returns unexpected results: internal
index => associated object instead of object => associated data. 

Reproduce code:
---------------
<?php
$spl = new SplObjectStorage ();
$spl[new StdClass ()] = 'a';
$spl[new StdClass ()] = 'b';
foreach ($spl as $object => $data)
{
        var_dump ($object, $data);
}
?>

Expected result:
----------------
object(stdClass)#2 (0) {
}
string(1) "a"
object(stdClass)#3 (0) {
}
string(1) "b"

Actual result:
--------------
int(0)
object(stdClass)#2 (0) {
}
int(1)
object(stdClass)#2 (0) {
}
