I do not really understand what all this is about, but:
package What is
type Void (<>) is private;
function Create (Params: Some_Type) return Void is abstract;
private
type Void is null record; -- no values
end What;
Void has no values (hm, a null record is a value, but it's irrelevant, since no objects exist (there is none in the private part; a body is illegal); no objects can be created because Create is abstract, so in effect Create does not exist - so it cannot be called.
With caveat - I didn't try to compile this.
