Though the "with type ... is access" part is not included
in the current ARG proposal (and it is still a "work item"
rather than in the "approved" state).

The current ARG proposal has "with type P.T;" and "with type P.T is tagged;"
as two possible "with type" clauses.  An anonymous access type
has also been proposed of the form "P.T'Class_Access".  Together
these two proposals approximate the "with type ... is access" feature.
