It's more work for the sender, but the receiver still has to do the same amount of work as before to get back to actual pointers. So it seems like pointless work. Having actual interior pointers means not having to deal with pointers as offsets when using these objects. Now the programming language could hide those details, but that means knowing or keeping track of the root object whenever traversing those interior pointers, which could be annoying, or else encoding an offset to the root and an offset to the pointed-to-item, which would be ok, and then the programming language can totally hide the fact that interior pointers are offset pairs. I've a feeling that fixing up pointers is the more interoperable approach, but it's true that it does more memory writes. In any case all interior pointers have to be validated on receiving -- I don't see how to avoid that (bummer). What a fun sub-thread.
