| * @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
