A `Char.T` is an `CHAR`. This interface is intended to be used as an actual interface for generic interfaces and modules such as `Table`.

    INTERFACE Char;

    IMPORT Word;

    TYPE T = CHAR;

    CONST Brand = "Char";

    PROCEDURE Compare (a, b: T): [-1..1];

== RETURN (a - b)

    PROCEDURE Equal (a, b: T): BOOLEAN;

== RETURN (a = b)

    PROCEDURE Hash (a: T): Word.T;

== RETURN ORD (a)

    END Char.
