Description:
------------
When sending some recursion variable to var_export it gets "Fatal error: Nesting level too deep - recursive dependency?" while var_dump inform of *RECURSION*. I'm not sure it is a bug, but i think it worth thinking of changing.
CLI output:
php > class a { };
php > $a = new a();
php > $a->a = &$a;
php > var_dump($a);
object(a)#1 (1) {
  ["a"]=>
  &object(a)#1 (1) {
    ["a"]=>
    *RECURSION*
  }
}
php > var_export($a);

   'a' =>
  a::__set_state(array(
     'a' =>
    a::__set_state(array(
       'a' =>
