I am not a language lawyer (at least with respect to c) but it seems that the
intent of the committee in n1111 was to limit when you were "looking at" a union,
Dr 257 seems to be only talking about what you are allowed to do if you are
looking at a union.
It seems to me that if you are not looking at a union, and this seems clearly
where n1111 was going, that the subsequence rule could not be applied.
