What we really need is a get_hash_t handler on the object, so that each
object knows how to hash itself. This can also come in handy when using
objects as array keys.

Hello Andrey,
wrong assumption. That is only the handle but only the handle+handler
combination is unique.

Wonderful idea Helly!

However, I think you are wrong that it cannot be implemented in user
land with O(1)
complexity. The following one-liner should give you a hint why I
think it is possible.
[EMAIL PROTECTED]:~/test> php -r 'class a{} function get_hash_key($obj){
ob_start();
var_dump($obj); $v=ob_get_contents();
ob_end_clean();var_dump(substr($v, 7, strpos($v, "
", 11) - 7));} get_hash_key(new a);'
string(4) "a)#1"
The string is unique per object. ) and # are noise but they are not a
problem.
Best wishes,
Andrey
