--TEST--
Iteration over SplDoublyLinkedList via 'foreach' does not change direction partway
--FILE--
<?php
$list = new SplDoublyLinkedList();
$list->push(1);
$list->push(2);
$list->push(3);
/* SplDoublyLinkedList would previously check the iteration mode *each time*
it would advance to the next item in a 'foreach' loop
This meant that it could move forward, then backward, then forward if the
iteration mode was changed in the middle of a loop */
