  // public member functions
  const std::type_info & value_type() const;


Base class for all option that have a fixed type, and are willing to announce this type to the outside world. Any 'value_semantics' for which you want to find out the type can be dynamic_cast-ed to typed_value_base. If conversion succeeds, the 'type' method can be called.
