Tie & Field Access

to_tie(obj) returns a compile-time tuple of field references:

auto t = ureflect::to_tie(u);
auto std_tuple = ureflect::as_std_tuple(t);

std::apply([](auto&... f){
    ((std::cout << f << ' '), ...);
}, std_tuple);

This is equivalent to std::tie(obj.field1, obj.field2, ...) but generated automatically.
