template<typename SequenceSequenceT, typename Range1T>
  range_value< SequenceSequenceT >::type
  join(const SequenceSequenceT & Input, const Range1T & Separator);

template<typename SequenceSequenceT, typename Range1T, typename PredicateT>
  range_value< SequenceSequenceT >::type
  join_if(const SequenceSequenceT & Input, const Range1T & Separator,PredicateT Pred);template<typename SequenceSequenceT, typename R
