|
| * A constant expression is one of the following:
|
| * . . .
|
| * • A literal string where any interpolated expression is a compile-time
|
| * constant that evaluates to a numeric, string or boolean value or to null.
|
| * @description Checks that a string literal that involves string interpolation,
|
| * that evaluates to a numeric value, but not a constant expression,
|
| * cannot be assigned to a constant variable.
