    template<class T>
    struct is_unscoped_enum
        : __tof { };

__inherit If T is a (possibly cv-qualified) unscoped enumeration type
(`enum` but not `enum class`), then inherits from __true_type, otherwise
inherits from __false_type.

__examples

[:Given: `enum color { red, blue };` and `enum class fruit { apple, orange };`]

[:`is_unscoped_enum<color>` inherits from `__true_type`.]

[:`is_unscoped_enum<fruit>` inherits from `__false_type`.]

[:`is_unscoped_enum<color const>::type` is the type `__true_type`.]

[:`is_unscoped_enum<color>::value` is an integral constant expression that
evaluates to /true/.]

[:`is_unscoped_enum<color&>::value` is an integral constant expression that
evaluates to /false/.]

[:`is_unscoped_enum<color*>::value` is an integral constant expression that
evaluates to /false/.]

[:`is_unscoped_enum<T>::value_type` is the type `bool`.]
