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> > ).
