I've seen in the CVS that the casts are to support enums. But the
documentation for integral_c says

     An Integral Constant is a class (or a template class)
     that represents a value of a built-in integral type

Enumerations are not integral types. Also, the presence of next and
prior exposes the use with enumerators to undefined behavior. Do we
really want that?

Genny.
