/** // This function is deprecated, use format instead.
\rst FMT_DEPRECATED(Formatter<> Format(StringRef format));
Formats a string similarly to Python's `str.format
<http://docs.python.org/3/library/stdtypes.html#str.format>`__ function.
Returns a temporary :cpp:class:`fmt::Formatter` object that accepts arguments
via operator ``<<``.
*format* is a format string that contains literal text and replacement
fields surrounded by braces ``{}``. The formatter object replaces the
fields with formatted arguments and stores the output in a memory buffer.
The content of the buffer can be converted to ``std::string`` with
:cpp:func:`fmt::str()` or accessed as a C string with
:cpp:func:`fmt::c_str()`.
**Example**::
std::string message = str(Format("The answer is {}") << 42);
See also `Format String Syntax`_.
