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

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

We can\'t change this by adding some text when this happens, as that would not result in valid PHP code in that case (which is the purpose of this function).
