thank you for reporting this. case object/object variants is always an interesting subject for serializer library. it is tricky to do it properly automatically.
work-around: you can provide a custom deserializer for your special object, e.g:
proc unpack_type*[ByteStream](s: ByteStream, x: var FooBarMsg) =
let numFields = s.unpack_array() # or unpack_map if you use OBJ_TO_MAP version
let kind = MsgType(s.unpack_imp_int64())
x = FooBarMsg(kind: kind)
case kind:
of MSG_FOO : s.unpack(x.foo)
of MSG_BAR : s.unpack(x.bar)
EDIT: you can use stringify
to debug the msgpack binary data.

@jangko thank you very much for the workaround suggestion. That works.
I agree that object variant handling is tough to implement correctly and generally, so please feel free to close the issue if you feel that it makes sense to do so.
