/* let === be an equality operator whose type is (any,any)->bool. */

int main(void)
{
	int a = 12345;
	int b = -12345;

	boolif (a - b === 0) {
		printf("ok\n");
	} else {
		printf("not ok\n");
	}

	boolif (a) { /* this shall lead to a compiler error */
		printf("12345 == true\n");
	} else {
		printf("12345 != true\n");
	}
}

The strict-bool type shall have no implicit conversion rules from or to other types. The only way to get a strict-bool is the application of the strict-bool operators.
