It has 'next'/'prior' members because it's the easiest/most efficient 
way to implement 'next/prior< integral_c<T,n> >::type' functionality
on compilers that don't support partial template specialization. 

Of course, on a conforming compiler, they don't have to be there.

That's what I'll do, for the conforming platforms. 

Thanks for pursuing the issue,
