This problem can be solved by a type class.

Since their creation, many other applications of type classes have been discovered.

The type system supports type classes, inspired directly by the Haskell language.

The type class, in turn, contains the function from which a string representation of the object can be generated.

A type family declared inside a type class is called an associated type.

In order to integrate an organization with individual needs there must be an ideal type class.

Accordingly, much of the work in extending the language has been directed towards types and type classes.

A type class may be parametrized on more than one type.

Thus a type class can describe not only a set of types, but an n-ary relation on types.

Type families, as described above, may also be associated with a type class.
