No, because the page requires T to be an arbitrary *integral* type,
and according to the standard I have (section 3.9.1 Fundamental Types,
para. 7), an enumeration is NOT an integral type, and all the
integral types do have integral_rank<T> defined in largest_int.hpp.

I'd still like something corresponding to range_c for enumerations.
Any chance of that?
