I think it should just be simple functions:

template <int N, typename Sequence>
char const* name_at_c(Sequence const& seq);

template <typename N, typename Sequence>
char const* name_at(Sequence const& seq);

There should be a compile error if Sequence has no named members.
Some types of sequences may implement it through a customization
point (same scheme that at_c and friends use).
