I tried this approach as well :) I called it a 'cast_iterator'. However, writing a full iterator class is involved, especially if you don't want to restrict the iterator class to 'input_iterator_tag'. Second, I felt it was 'writing to the implementation'. I know that libstdc++ uses the 'value_type' to determine the type, but this doesn't mean other implementations use it! In the end, it is a non-solution. If you've want the non-expanding behaviour, this will always be possible by simply using a function object. For example; std::partial_sum(begin, end, std::plus<char>()) This is *guaranteed* not to expand. ~Marc. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22634
