Well, things like:

    #
    # Read the array 'data' as a String
    #
    def getString_data(self):
        carr = "";
        for i in range(0, 4000):
            if self.getElement_data(i) == chr(0):
                break
            carr += self.getElement_data(i)
        return carr

in MIG output;

missing proper getters and setters in Message for self.data, etc.

That's why I said that this is "nice to have" :)
