What ends up being stored in the array is the hash, not the object. And there is no immediate way of getting the key object back. The user writes: $arr = array($obj => 2); but key($arr) returns the hash only. As I said in the original discussion: this RFC is actually about having an implicit call to __hash() whenever an object is used as an array key. You can achieve exactly the same in userland with an explicit call. I would rather wait (maybe indefinitely) to have a proper implementation of objects as keys than have this compromise. Best,
