/**
\rst
A ``printf`` argument formatter based on the `curiously recurring template
pattern <http://en.wikipedia.org/wiki/Curiously_recurring_template_pattern>`_.
To use `~fmt::BasicPrintfArgFormatter` define a subclass that implements some
or all of the visit methods with the same signatures as the methods in
`~fmt::ArgVisitor`, for example, `~fmt::ArgVisitor::visit_int()`.
Pass the subclass as the *Impl* template parameter. When a formatting
function processes an argument, it will dispatch to a visit method
specific to the argument type. For example, if the argument type is
``double`` then the `~fmt::ArgVisitor::visit_double()` method of a subclass
will be called. If the subclass doesn't contain a method with this signature,
then a corresponding method of `~fmt::BasicPrintfArgFormatter` or its
superclass will be called.
