Not really :-)

It exists as such in QtDBus code:
bool QDBusMarshaller::appendCrossMarshalling(QDBusDemarshaller 
*demarshaller)
{
    int code = dbus_message_iter_get_arg_type(&demarshaller->iterator);
    if (dbus_type_is_basic(code)) {
        // easy: just append
        // do exactly like the D-BUS docs suggest
        // (see apidocs for dbus_message_iter_get_basic)

        qlonglong value;
        dbus_message_iter_get_basic(&demarshaller->iterator, &value);
        dbus_message_iter_next(&demarshaller->iterator);
        dbus_message_iter_append_basic(&iterator, code, &value);
        return true;
    }

    [.... other, more complex types follow ...]
}

This is a real use-case situation due to the way the lazy demarshaller 
works.
