Well, "arrays" are implemented as hash tables, hash tables work by
generating a hash to identify a value. Changing this is a big change
(rewrite everything accessing array keys) and you can always do
something like

$array = array(
  spl_object_hash($object1) => array('object' => $object1, 'data' => /* ...*/),
  spl_object_hash($object2) => array('object' => $object2, 'data' => /* ...*/),
 /*...*/
);

The only thing I can imagine is that we add support for objects
implementing ArrayAccess and Traversable (Iterator) on more places.
