Is the following supposed to compile:

enum visitor_numerals { visitor_n0 , visitor_n1 };

typedef mpl::vector_c<visitor_numerals,visitor_n0> vec_viz_type; typedef mpl::at_c<vec_viz_type,0>::type vec_viz0_type;

Theoretically, I see no good reason to disallow it.

I think that one major problem is that you promise next<> and prev<> on integrals. It would be quite problematic to satisfy this for enums staying in the same enum type. Regards, Arkadiy
