It can serialize most of the available types in D, including third party types and can serialize through base class references. It supports fully automatic serialization of all supported types and also supports several ways to customize the serialization. Orange has a separate front end (the serializer) and back end (the archive) making it possible for the user to create new archive types that can be used with the existing serializer.

I think I better understand now what MessagePack is and I agree that our libraries have different goals/uses.
