[boost] [iochain] Overloaded >> and << operators?

Hi, Reading through the documentation for the Boost.Iochain library, I do not see that any default >> and << operators have been provided. I would expect to be able to use these to stream data out of a stream and into a stream, respectively. An example of the >> operator would be below: template< typename t_type > source& operator>> ( source& stream, t_type& data ) { stream.read( data ); return stream; }
