Hi,

Consider a map defined as...

std::map< int, std::list< std::string > > my_map;

I'm wondering if/how it's possible to use Boost.Range to call a function on
each std::string in each of the lists contained in the map. I have an
implementation below which works using a C++0x lambda function but am
curious if this can be done purely using Boost.Range?

boost::for_each(
boost::adaptors::values( my_map),
[]( const std::list< std::string >& my_list ) { boost::for_each( my_list,
some_func ); } );

ideas anyone?
