Comment (by giecrilj@…):

 Syntax:: `(cout << separated (range, " "))`

 == Implementation ==

 {{{
 #!c++

 namespace boost
 {
 namespace detail
 {
 template < class P_R, class P_C >
 struct output_range
 {
 typedef P_R range_type; typedef P_C char_type;
   range_type const &m_range; char_type const *m_sep;
   inline output_range
   (range_type const &p_r, char_type const p_s [])
     :m_range (p_r), m_sep (p_s) {}};
   template < class P_R, class P_C, class P_T >
   inline ::std ::basic_ostream < P_C, P_T >
