boost::operator<< — Provides streaming output for variant types.
// In header: <boost/variant/variant.hpp> template<typename ElemType, typename Traits, typename T1, typename T2, ..., typename TN> std::basic_ostream<ElemType,Traits> & operator<<(std::basic_ostream<ElemType,Traits> & out, const variant<T1, T2, ..., TN> & rhs);
| Requires: | Every bounded type of the variantmust
          fulfill the requirements of the
          OutputStreamable
          concept. | 
| Effects: | Calls out << x, wherexis
          the content ofrhs. | 
| Notes: | Not available when BOOST_NO_IOSTREAMis
          defined. |
