You don't use empty() on objects.

      <div>Heh, to quote a great movie: That's just like, your opinion,
        man. In all seriousness, there are quite a number of uses for
        ==, especially because we don't have operators on objects, nor
        do we have value objects. Sometimes, equality isn't based on
        identity, but on value:<br>
