It would work, but it seems like overkill. In particular, there's no
intention to extend it any further, and all symbol versions do the
same thing, call find-ns and delegate, so maybe just adding a let
level to the existing fns is best:
(let [ns (the-ns ns)] ...)
where the-ns x is just (if (instance? Namespace x) x (find-ns x))
