| <p>A guard predicate should not throw any exceptions. |
| Yet, any exception thrown within a guard predicate cause the guard to evaluate to <code>false</code> |
| rather than propagating the exception, meaning that the evaluation of a guard predicate will never |
| interrupt the current base behaviour.<br /> |
| A compiler should flag any checked exception that is thrown within a guard. |
| Such diagnosis should by default be treated as an error, with the option of configuring |
| its severity to warning or ignore. |
