Sure but what do you imagine in terms of a serialization library?

Obviously, *you* could serialize your pointer, for example as index in
the list, but all that the serialization library sees is a pointer. It
has no way of knowing that it points an element within the list, it
has no way of knowing that there is a list even. But maybe I'm missing
something so I asked how would that work.
