Not having any objects at all needs to be a feature of the
Ada language's type system, at least for this kind of competition.
(Hence hiding the full type in a private nest with no body.)

The members of the functionist faction will turn their eyes
towards the cieling in dispair:
it is these weird functions involving uninhabited types that have
turned out to be essential for the interplay between logicians
and computer scientists discovering practical solutions. For
example, what about a type system that guarantees termination?
