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)

(the address points directly to a .zip file in the Yahoo! files
section - downloading will likely require that you have a Yahoo!

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.
