#include <string>

namespace implementation 
{
    template <typename T>
    inline auto stringify(const T& t) -> std::string
    {
        return std::to_string(t);
    }

    inline auto stringify(const char* str) -> std::string
    {
        return str;
    }


    inline auto stringify(const std::string& str) -> std::string
    {
        return str;
    }
}

template <typename ... T>
auto format(T ... args) -> std::string
{
    return (... + implementation::stringify(args));
}
