for debug only:
This has been discussed before with the result that there is a flag (is_ref I think) indicating that a variable is a reference. Well, there are currently some problems with references and it could be handy to have a function that check whether a variable is a reference.
eg. get_object_vars() then sorting out all references with is_reference() and display their names so that you?re able to kill the circular reference of them before displaying

As was discussed on the list, is_ref is something very different, and it's not really possible to know if the variable "is reference" or not.
