Nested 'switch' statement

Reports nested switch statements or expressions.

Nested switch statements may result in extremely confusing code. These statements may be extracted to a separate method.

Example:

  int res = switch (i) {
            case 0 -> 0;
            default -> switch (i) {
                case 100 -> 0;
                default -> i;
            };
        };
