| /// @assertion An on-catch clause of the form on T catch (p1) s is equivalent to |
| /// an on-catch clause on T catch (p1, p2) s where p2 is an identiier that does |
| /// not occur anywhere else in the program. |
| /// @description Checks that it is not an error when the least specific catch |
| /// clause is placed first, followed by more specific, and therefore redundant, |
| /// catch clauses and that an exception can not be caught with clauses that don't |
| /// match. |
