boost::unwrap_recursive_wrapper — Unwraps the specified argument if given a specialization of
recursive_wrapper.
// In header: <boost/variant/recursive_wrapper.hpp> template<typename T> class unwrap_recursive_wrapper { public: // types typedef unspecified type; };

T is a specialization of

type is equivalent to T.
