| * @assertion The [&&] operator is now short-circuit in constant and potentially |
| * constant expressions. It only attempts to evaluate the second operand if the |
| * first operand evaluates to [true]. This makes [false && (null as |
| * String).length] a valid constant expression. The second operand expression |
| * still needs to be a potentially constant expression, which is a new use of |
| * potentially constant expressions outside of [const] constructor initializer |
| * lists. |
| * @description Checks that compile error is thrown if the first [&&] operand is |
| * [false] and the second one is not [bool] in the constant expression. |
