As it was already suggested it will dispatch after dereferncing. In Ada
2005 which seems you are using, you will not need P.all with prefix
notation: Node.Next.Next, Next(Node).Next, both Next in both variants
dispatch.
Alternatively you can use tagged handles to nodes wrapping an access type.
The operations on nodes become private. The operations on handles are
public.
