Then, if we wanted to make a really user-friendly interface, we could add

boost::iterator_range<...>
boost::directory_range( const boost::path&, const boost::path& extension )

support for multiple extensions or reguar expression would be cool, e.g.

    boost::directory_range( "some_path/", "(.txt|.doc|.jpg)" )

and support for the reverse sitution

boost::iterator_range<...>
boost::directory_range( const boost::path&, const boost::regex& toExclude )

Especially for recursive iteration, it is useful to skip entire directories.

Remark: such support is probably most naturally added to the underying 
iterator classes by storing some boost::optional<> variables.
