You could conceivably write a child class that wraps or

class Serializer {
    void serialize(Serializable s) {}
}

class ExtendedSerializer: Serializer {
    override void serialize(Object o) {
        super.serialize(reflectToSerializable(o));
    }
}


But you can't do that in D either, or? (I am ok with it, having 
invariant parameters is an ok tradeoff).
