"In a nutshell" one can do the following: for_each(a.begin(), a.end(), std::cout << _1 << ' ');

You can cout the contents of container a with spaces between using: copy( a.begin(), a.end(), ostream_iterator< a::value_type >( cout, ' ' ) ); No boost required. Hopefully someone with more boost experience can give an elegant solution for a more general case ( such as your map< string, list<int> > ). - Scott McMurray
