How do I use heterogeneous lookup with std::array?

Heterogeneous lookup in C++ allows you to access elements in an array without the need for type casting, improving code readability and safety. By using `std::array`, you can benefit from fixed-size arrays and better type safety. Below is an example demonstrating how to use heterogeneous lookup with `std::array`.


        #include 
        #include 
        #include 
        
        int main() {
            std::array<:variant std::string>, 5> arr = {
                42,
                "Hello",
                100,
                "World",
                7
            };
            
            for (const auto& element : arr) {
                std::visit([](auto&& arg) {
                    std::cout << arg << std::endl;
                }, element);
            }
            return 0;
        }
