  In C++ you could use the boost format library, which allows you to do
things like this:

    std::cout << boost::format("writing %1%, x=%2% : %3%-th try")
                 % "toto" % 40.23 % 50;

  (OTOH I'm guessing this is less efficient than the direct approach.)

  Which is inconvenient if you need to use some format specifiers (such
as printing at least 5 digits, with leading zeros).
