Ok, then I just change "register" to a static method.

A static method of whom?

Andrei

Well, "register" currently an instance method of Serializer so I would
change it to be a static method of Serializer.

I think the ability of a class to be serialized would be independent of
the notion of a serializer. To me, "this class is serializable" really
means "this class has metadata associated with it that allows interested
parties to serialize it". But perhaps this is splitting hairs.

Andrei

You don't want to have it in the class and don't want it in the
serializer. I mean, it needs to be stored somewhere and I thought that a
static method in Serializer would better than a completely global function.

Are you thinking about having another serialization library that can use
this information as well? I'm not sure if that's good idea, different
serialization implementations might need to do very different things
with the information.

It could be used for network transmissions. Correct me if I'm wrong but Orange serializes the entire object. When sending things over the network or when saving something to disk for that matter you most likely are only interested in serializing some of the fields of an object. I really think it would be nice to declaratively mark fields as serializable for certain purposes e.g.:

class Foo {
        int a;         // Send over network and saved to file
        int b;         // Saved to file
        ubyte[] cache; // not to be serialized
}

mixin(serialize!(Network, Foo, a);

mixin(serialize!(File, Foo, a);
mixin(serialize!(File, Foo, b);

// but still support not specifying each field
class Bar { int a; }
mixin(serialize!(File, Bar));


Another way would be to just declare a class as serializable and then for each serialization type (ie. Network, File) declare that they should skip a field. Actually I think I better like this approach since it would allow decoupling of serialization type and the declaration of serializability.
