46 /// utils::format::formatter objects shorter, and thus to allow inlining these
47 /// calls right in where formatted strings are required.  A typical usage would
48 /// look like:
49 ///
50 /// \code
51 /// std::cout << F("%s %d\n") % my_str % my_int;
52 /// \endcode

54 /// \param fmt The format string.
