| * @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 | |
