- [:`is_volatile<volatile int>` inherits from `__true_type`.]
- [:`is_volatile<const volatile int>::type` is the type `__true_type`.]
- [:`is_volatile<int* volatile>::value` is an integral constant
- expression that evaluates to /true/.]
- [:`is_volatile<int volatile*>::value` is an integral constant
- expression that evaluates to /false/: the volatile qualifier is not
- at the top level in this case.]
- [:`is_volatile<T>::value_type` is the type `bool`.]
