In this case there's no need for a macro. Just use:

  using boost::serialization::make_nvp;

  ar & make_nvp( "variable", m_variable);

What would be useful (for me ) would be a macro that used a user defined
default for the prefix. We use CamelCase type names here.

   #define BOOST_SERIALIZATION_NVP_PREFIX_DEFAULT m

   ar & BOOST_SERIALIZATION_NVP_PREFIXED( Variable );

Which would be equivalent to:

   ar & make_nvp( "Variable", mVariable);

But, looking at it now, the non-macro version is more readable, flexible and
fewer characters to boot.
