/** \def BOOST_VMD_EMPTY(...)

    \brief Outputs emptiness.

    ... = any variadic parameters. The parameters are ignored.
    
    This macro is used to output emptiness ( nothing ) no matter
    what is passed to it.
    
    If you use this macro to return a result, as in 'result BOOST_VMD_EMPTY'
    subsequently invoked, you should surround the result with 
    BOOST_VMD_IDENTITY_RESULT to smooth over a VC++ problem.
