How about the following with plain syntax? :-)

some_algorithm(
     file_range<boost::uint8_t>(name) |      // file_iterator range
         utf8_decoded |                      // u8_to_u32_iterator range
         transformed(::newline_cvter()) |    // transform_iterator range
         tab_expanded(::tabsize<>::value) |  // my buggy iterator
         to_upper |
         memoized                            // multi_pass iterator range
);
