Lots of ways, and many are not even hacks <wink>.

One of these might suit:

  boost::tuple<
        std::string, int, float,
            std::map<std::string,std::string>, 
            std::vector<std::vector<std::vector<int> > > >

or

  std::vector<boost::any>

so is (a and [b] or [c])[0] <wink>
