Comment (by hakre):

 To demonstrate an overwrite, see this example:

 {{{
 $one = array('num' => 1);
 $input = array( &$one, &$one );

 $nums = wp_list_pluck($input, 'num');

 var_dump($nums, $input);
 }}}

 will do notices on trunk and set both keys to NULL in `$nums`.

 But I still can not see how that should apply to `$wp_query->comments` (I
 didn't get it filled in my test script either, just asking).
