A Class Template Specialization
Explore class template specialization in C++20 by learning how to enforce type requirements using concepts. Understand how to restrict template parameter types and benefit from meaningful compiler error messages when constraints are violated. This lesson helps you create safer, more expressive generic code through custom type validation.

Require a nested type
Just like for the nested types, we have to use the keyword typename along with the specialized class template that is expected to be a valid specialization:
template<typename T>
concept TypeRequirement = requires {
typename Other<T>;
};
In this case, the concept ...
