Since I didn't watch this thread closely I don't know if you're talking about recent addition to boost.type_traits (http://lists.boost.org/boost-announce/2006/04/0084.php) or something completely different. My guess is that you use different version of promotion traits in VIGRA. Is it correct?
Yes. Originally, I learned the concept from the blitz++ library.
