Seems reasonable to me.

Hm.  The docs aren't too consistent either: there are several other nearby
places that say "keys".  Notably, the functions json[b]_object_keys() have
that usage embedded in their names, where we can't readily change it.

I'm inclined to think we should s/names/keys/ in the docs instead.
Thoughts?
