I have read the mailing list. I think all filtering should be moved to the directory iterators and that the helper functions should only be used for passing parameters to the iterator constructor like this:

template<class... argts>
boost::iterator_range<directory_iterator>
directory_range(argts... args){
    return boost::iterator_range<directory_iterator>(
        directory_iterator(args...),
        directory_iterator()
    );
}
template<class... argts>
boost::iterator_range<recursive_directory_iterator>
recursive_directory_range(argts... args){
    return boost::iterator_range<recursive_directory_iterator(
        recursive_directory_iterator(args...),
        recursive_directory_iterator()
    );
}

Note that because directory_iterator supports begin()/end(), one can already use range-for loops like this:

for( const auto& dir_ent : directory_iterator{ "my/path/to/iterate" } )
{
    cout << dir_ent.path() << '\n';
}
