I think you mean novice use. There are certainly times when assigning an object to a variable I want all the values currently referring to that object to see the update and not just the variable being assigned to. I understand that objects in PHP5 are passed by reference under normal assignment, but it's a copy of a reference and not a reference to a reference.
