Yep, that works for single-level data structures like the list of users
for a group.  But [obviously] the cast does not recurse so other
structures need to have all their child keys cast as well.  It just
seems awkward.

    public function getData($gid)
    {
        $response = $this->_server->request('group.getdata',
array($gid));
        $data = array();
        $data['name']  = $response->result->name;
        $data['email'] = $response->result->email;
        $data['users'] = (array) $response->result->users;
        return $data;
    }
