/** | |
* @assertion A constant expression is an expression whose value can never | |
* change, and that can be evaluated entirely at compile time. | |
* A constant expression is one of the following: | |
* . . . | |
* • An expression of the form e1 + e2 where e1 and e2 are constant expressions | |
* that evaluate to a numeric or string value or to null. | |
* • An expression of one of the forms −e, e1 - e2, e1 * e2, e1 / e2, e1 ˜/ e2, | |
* e1 > e2, e1 < e2, e1 >= e2, e1 <= e2 or e1 % e2, where e, e1 and e2 are | |
* constant expressions that evaluate to a numeric value or to null. | |
* @description Checks that an expression of the form e1 + e2 cannot be used to | |
* initialize a constant variable if e1 is integer and e2 is a string. | |
