* @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 [&&] does not attempt to calculate the second
* operand of [&&] operation if the first one is [false] in the potentially
* constant expression.
