Yes, maybe. But we should at least make the id() a derived property
for Mesh. We can put the unique_id member variable and the id member
function in a separate class named "ID" (or similar). Then Mesh can
derive from both Variable and ID. That way, we can easily add the
property to other classes when we need it.
