And has at least one major drawback: The object itself is not in the array, you cannot retrieve it by foreach($arr as $obj => $v) { }. => This is quite counter-intuitive and counter-productive: one would expect to find the object there, not its "hash". As others noted, it also prevents a full-fledged objects-as-key implementation in the future. In the end it causes issues and brings very little compared to an explicit call to convert an object to a key. -1 -- Etienne Kneuss
