// Without BOOST_PP_VARIADICS support :
BOOST_FUSION_ADAPT_STRUCT(
    demo::employee,
    (BOOST_FUSION_ADAPT_AUTO, name)
    (BOOST_FUSION_ADAPT_AUTO, age)
)
Both signatures works on BOOST_PP_VARIADICS enabled compilers. Actually
BOOST_FUSION_ADAPT_AUTO expands to BOOST_PP_EMPTY().
Perhaps, 'auto' would be shorter?
BOOST_FUSION_ADAPT_STRUCT(
     demo::employee,
     (auto, name)
     (auto, age)
 )
It also looks kind of similar to C++14 lambdas.
That looks nice, and it may be great, but I'm a bit concerned in giving
a slight different meaning than the official one to a standard keyword.
Could you describe the difference?
