> FWIW, (simple)json module serializes subclasses of builtin types > just as expected. Does that round trip properly? For instance, if you serialize an instance of a list subclass does it unserialize as a list instance or as the subclass? Perhaps JSON has some way of supporting a user-defined set of types. XML-RPC has no way to do that, and feeding in an instance of a subtype then getting the base type out on the other end was deemed a bad thing.

Does that round trip properly?  For instance, if you serialize an
instance of a list subclass does it unserialize as a list instance
or as the subclass?
