Hi Boris,

As Jonathan has pointed out, my library is aimed at solving this type of 
problem. Your example would become:

#include <sstream>
#include <boost/outfmt/stl/vector.hpp>
#include <boost/outfmt/stl/pair.hpp>

int main()
{
   typedef std::pair< std::string, std::vector< int > > element;
   element one, other;

   one.first = "Meine \"Grosse\" Welt!";
   one.second.push_back( 3 );
   one.second.push_back( 6 );
   one.second.push_back( 9 );

   std::stringstream ss;
   ss << one;
   std::cout << "written: " << ss.str() << '\n';
   ss >> other;
   std::cout << "read: " << other << '\n';

   return( 0 );
}

Providing a much simpler syntax and stream integration. The output for this 
is:
   written: ( "Meine \"Grosse\" Welt!", [ 3, 6, 9 ] )
   read: ( "Meine \"Grosse\" Welt!", [ 3, 6, 9 ] )

It is possible to control how the pair and vector types are rendered using a 
custom formatter. Refer to the examples and documentation for more 
information.

Regards,
Reece
