| /// @assertion From the Constant-update-2018 Spec: |
| /// The operator [>>>] is now allowed in a potentially constant expression, and |
| /// it is valid in constant expression if its left and right operands are [int] |
| /// instances, and the operation doesn't throw. The [>>>] operator has not been |
| /// added to the [int] class yet, so unless the left-hand operand's static type |
| /// is [dynamic], the program will still be rejected. When the operator is added, |
| /// it should then also work in a constant expression. |
| /// @description Checks that arguments of [>>>] operator should be int. |
