Is there no way to provide the member names at compile time? There must be something obvious and I am just not seeing it. name will obviously be char* and you can't have that in a template

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).
The function argument would not be necessary, wouldn't it? All the information is available in the type Sequence. template <int N, typename Sequence> char const* name_at_c(); This would then be at runtime, not compile time?. rds,
