I am not so sure. I think that "type Count is (<>);" is logically
flawed. Here (<>) is a class of types, so Count is an object of this
"type type".Thus it would be natural to have:
Count : (<>) := Natural;
A similar thing could be done with subprograms. And of course, we
should have subprogram types! At least to reduce use of nasty
access-to-subprogram objects.
