public interface Function
extends Functor

A functor that encapsulates the unary function f/1 which is kind of the most general Functor. Like "r = f(a)" it applies on

The set of all functions (or maps) of type A→B is called Map(A,B) = BA. For any cardinalities of A,B, it is in fact true that |BA| = |B||A|. These functions of Map(A,B) have the form

f: A→B; a ↦ f(a)
