thank you. i don't even thought how that can be done. i guess that Data values contains two parts - describing type (Constr?) and value itself. Serializing value is even easier than (already implemented) gshow/gread, and if it can use Binary instance instead of general algorithm whenever possible, it would be ideal Constr (or some type representation) is just value of some type, after all. So, for it's serialization we can use either gshow/gread, or general binary serialization algorithm, or make custom Binary instance that is the general thoughts, i hope that someone knowing better this infrastructure will explain this dark area to me > I don't see how this can work for arbitrary types without auto- > generating the serialization code.
