struct alien {
    std::string color_;
    std::string planet_;
    bool benevolent_;
};

BOOST_FUSION_ADAPT_STRUCT(
    alien,
    (std::string, color_)
    (std::string, planet_)
    (bool, benevolent_)
)

I know how I can get to the actual member values, i.e. I could check
at<2>(anAlien) to see if I should run away or not.
But what if I wanted to get to the member names? (In this example it would
be "color_", "planet_" and "benevolent_")
It could be very useful for example for serialization that stores not just
values but also the names of the values.
Printing structures to stdout for inspection would be a breeze too.
Since BOOST_FUSION_ADAPT_STRUCT is a macro, surely the member names could
be strigized and stored somewhere.

Thanks,
     Andy.
