Or maybe integral_rank<T> can be modified similar to:
template<> struct integral_rank<long>           : int_<10>
{
     static long const max_value=LONG_MAX;
     static long const min_value=LONG_MIN;
};

where LONG_MAX and LONG_MIN are, I guess, macros defined in
<climits.hpp>.  I guess this is where LONG_MAX in:

   boost/mpl/aux_/preprocessed/plain/vector_c.hpp

comes from.

OTOH, it seems this is more of a type trait, and maybe such a definition
belongs in boost/type_traits.

Any thoughts?  I'd like to know where's the best place since I currently
have a use for it to replace the enum_size in:
