 Replying to [comment:6 ocean90]:
 > Based on [http://php.net/manual/en/book.spl.php PHP's manual]
 `ArrayObject` and `ArrayIterator` are part of SPL which can be disabled
 before 5.3. Looks like we need some class_exists() check here.

 Good question, but this isn't actually required in PHP starting with 5.1,
 as I just checked: http://3v4l.org/SkMVd

 The `instanceof` operator works on undefined classes in PHP≥5.1 as we can
 see there, so I don't think we need any `class_exists()` checks added.
