Yielding name along with the value is exactly path tracking. Plus, we iterate
over collections, and just values do not really resemble dataclass in the same
way just keys or just values don't resemble dict.
This is not the same with set/list/similar. You don't really need an index to
construct the collection. That said, I've been thinking of yielding index
exactly for path tracking (though this is of no use with sets).
