Good.  Can I ask one final clarification, please?  Then the following
should be koser in PHP 4 and 5, right?

    function &execute() {
        return new DB_result();
    }

Or would we need to do this to ensure proper opration in both versions?

    function &execute() {
        $tmp =& new DB_result();
        return $tmp;
    }

Or does the answer depend on what the constructor method does?  Or...?
