Reflection for C++26

Can I ask a naive question that consists of two parts and please don't flame me? lol

  * What type of problems static reflection could solve, in general?
  * Are there specific cases and / or situations where static reflection could resolve such case, even simplify an unnecessary complexity?

Any sort of reflection brings C++ one step closer to Python.

Implementing serialization for complex types often requires manual code writing or external tools. With static reflection you could automate this process

  template<typename T>
  void serialize(const T& obj, std::ostream& os) {
      for_each(reflect(T), [&](auto member) {
          os << member.name() << ": " << member.get(obj) << "\n";
      });
  }

Simplified property systems

    class Person {
    public:
        Person(const std::string& name, int age)
            : name(name), age(age) {}

        std::string getName() const { return name; }
        void setName(const std::string& name) { this->name = name; }

        int getAge() const { return age; }
        void setAge(int age) { this->age = age; }

    private:
        std::string name;
        int age;

        REFLECT_PROPERTIES(
            (name, "Name of the person"),
            (age, "Age of the person")
        )
    };

    int main() {
        Person person("Alice", 30);

        auto properties = reflect::getProperties<Person>();

        for (const auto& prop : properties) {
            std::cout << "Property: " << prop.name 
                    << " (" << prop.description << ")" << std::endl;
            
            auto value = reflect::get(person, prop.name);
            std::cout << "Value: " << value << std::endl;

            if (prop.name == "age") {
                reflect::set(person, prop.name, 31);
            }
        }

        std::cout << "Updated age: " << person.getAge() << std::endl;

        return 0;
    }

Simplified template metaprogramming

    template<typename T>
    void printTypeInfo() {
        constexpr auto info = reflect(T);
        std::cout << "Type name: " << info.name() << "\n";
        std::cout << "Member count: " << info.members().size() << "\n";
    }

Easier to write generic algorithms that work with arbitrary types

    template<typename T>
    void printAllMembers(const T& obj) {
        for_each(reflect(T), [&](auto member) {
            std::cout << member.name() << ": " << member.get(obj) << "\n";
        });
    }
