/**
 * @assertion A required formal parameter may be specied in one of three ways:
 *
 * • By means of a function signature that names the parameter and describes
 *   its type as a function type. It is a compile-time error if any default
 *   values are specied in the signature of such a function type.
 * • As an initializing formal, which is only valid as a parameter to a
 *   generative constructor.
 * • Via an ordinary variable declaration
 *
