/**
 * @assertion 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 operator [>>>] is accepted in constant expressions.
