I forgot to specify what seemed obvious to me: mystring() can be used
whenever you'd use string(), it would contain a operator string(). There is
no "manual" support for std::cout or anything else, it would just seamlessly
integrate with your existing string() code:

std::ifstream file(mystring("data%1.dat").arg(datFileNum, 3, true));
