 * Hi
 * Not sure that i’m posting in the correct area right now.
 * I do however have a problem when using the post_type parameter in both wp_list_pages
   and get_pages.
 * I have a custom post type set up and i want to list both ‘page’ and ‘my_post_type’.
   From what i can understand it’s not possible to send multiple values in the post_type
   parameter. So instead i try using the value ‘any’. But that fails aswell.
 * Simply put, this:
 *     ```
       $params = array('post_type'=>'any');
       var_dump(get_pages($params));
       ```
   
 * Returns **false** and gives a:
 * > ( ! ) Notice: Only variable references should be returned by reference in C:\
   > wamp\www\wp-includes\post.php on line 3394
 * While changing the post_type to ‘page’ works.
 * Is this a bug or is it intended? And how do i list both my custom post types 
   and the pages hierarchically?
 * Thanks
