AIUI, the RFC proposes that __hash() returns a string or an int, and
this value (not the object itself) will be stored and retrieved as key
of the array.

<https://wiki.php.net/rfc/objkey#proposal>:

| Create a new magic method, __hash() which is called when object is
| supplied as a hash key, and returns string or integer that is used as
| the hash key.
