Hi.

Is it possible to simplify valstat as:
template< typename T, typename S>
 using valstat = std::pair< std::optional<T>, std::optional<S> >;

or triplet version with additional info ( I ):
  template< typename T , typename S , typename I >
 using valstat = std::tuple< std::optional<T> , std::optional<S> ,
std::optional<I> >;
