The concept DerivedFrom<T, U>() is satisfied if and only if std::is_base_of<U, T>::value is true.
Notes
Despite the use of std::is_base_of in its description, DerivedFrom is not required to use it in its implementation. Thus, DerivedFrom<T, U>() may not normalize tostd::is_base_of<U,T>::value during partial ordering of constraints.
