Whenever an element is added, make sure it matches the correct type. All this does is add some flat overhead. I am also supportive of the idea of having generics, but I am not sure that the work it would take is worth it. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
