On the other hand, perhaps we should just have a general predicate for
this not-uncommon thing? `equal-or-member'? It would literally be
(defun equal-or-member (thing collection)
(or (equal thing collection)
(and (consp collection)
(member thing collection))))
We have a lot of data structures that can be lists or atoms, so I think
it might be generally useful...
