I have started trying to templatize c2_functions, but I have a question for the Boost group. Realistically, this class is fairly meaningless for anything other than double and long double types. I also have a long, enduring distaste for c++ templates and, as a result, little deep competence with them. The process of making it into working template classes which are also fairly easy to use will be very slow for me. For the 99% of users who will always use this with double, also, the need to declare every items with <double> after it, or even with <> for things which can be defaulted, is ugly and will likely reduce the user base. Would it be objectionable to the Boost concept to release a basic version of the which is strictly for doubles, with the knowledge that, for the few people who want it for long doubles, this can be done with a global search & substitute, and then to plan later for a successor to this which is fully templatized? I see this as a package which, in its current, template-free form, can be essentially spun off except for improving the documentation. The algorithms in it are simple and robust, and the code should be highly portable, so I doubt it will every need much maintenance. I think there is a fairly decent reason to make it available soon, since there appears to be a significant need for it, and to learn if real users need it structured differently. Marcus
