 * of one type (say 'first-name') to a value that expects another type (say 'last-name'), both of type string.
 *
 * @example
 * ```
 * @stringvalue class FirstName extends StringValue { first_name = discriminative }
 * @stringvalue class LastName extends StringValue { last_name = discriminative }
 * let a: FirstName = FirstName.from('Alice);
 * a = LastName.from('Jansen');   // ==> Will not compile
