/// @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 [&&] throws error if the first operand of [&&]
/// operation is [true] and the second one is not valid in the constant
/// expression.
