|
| * A constant expression is one of the following:
|
| * . . .
|
| * • An expression of one of the forms !e, e1 && e2 or e1 || e2, where e, e1
|
| * and e2 are constant expressions that evaluate to a boolean value.
|
| * @description Checks that an expression of the form !e cannot be used to
|
| * initialize a constant variable if e does not evaluate to a boolean value.
