Positive is the name of an abstract data type with values from 1 to
Integer'Last and operations inherited from the type, which name is Integer.

Type is a tuple: set of values x set of operations [with at least an
argument or result of the type].

Subtype is a type that inherits some operations (interface) of another
type, called "parent type," "base type," "ancestor type" or "supertype."

Subtyping relation is transitive and reflexive.

Class is the transitive closure of.
