I wrote it wrong in my previous post and it confused you, I meant to
say that we have a pointer-to-const that points a mutable object. In
other words, you can't modify the object through that pointer but when
the pointer is serialized there is no need to modify the object
through the pointer because in all cases the serialization library has
another pointer to the same object.
