A while ago I proposed adding a signed_traits class and then after receiving some input decided it better this be a property of some existing traits object, ideally "integer_traits" since only integer can be signed.
I tried to contact some people to whom I'd been referred about changing integer_traits.hpp but never heard back. Otherwise I have received no negative feedback from this proposal.
As Dave says, integer_traits<> reflects an obsolete approach to traits classes. My opinion is that we should refactor/rewrite most of its stuff. Also I would like it to not depend on numeric_limits. If you begin working at this, here are some small, self-contained, templates that could (well, some of them) fit into the new creature ;) (after making them mpl-compatible metafunctions) http://tinyurl.com/2w97t (the address points directly to a .zip file in the Yahoo! files section - downloading will likely require that you have a Yahoo! account) BTW, I also wrote a new version of static_log2 which has no dependency on numeric_limits and use a better algorithm (suggested, together with a reference implementation, by Vesa Karvonen) than the current one. It will be soon in the CVS. -- Genny.
