I did something like this some time ago.

    named_param p_name("name"), p_age("age");
    std::string your_name = get_your_name();
    unsigned int your_age = get_your_age();
    std::cout << format("{name} is {age} years old.\n",
                        p_name = your_name,
                        p_age = your_age);

IMHO, it's very useful feature.
