If I end up not serialising the pointee object, the framework does
serialise it automatically, right? That is to say:

  {
    A a;
    a.x = 5;
    ar << &a;
  }

  //...

  A *b
  ar >> b;
  assert(b->x == 5)

should work just fine, right?

That should work.

for symetry I would have written

{
    const A *a = new A(5);
    ...
    ar << a;
    ...
    A *new_a;
    ...
    ar >> new_a
    ..
    assert(*a == *new_a);
}

Note the slightly trick usage of const in this example which has been the
subject of recent posts and is explained in the manual section describing
tracking.
