Hi!
Suggested recursive impl:
(defn path-entries
([obj]
(path-entries [] obj))
([prefix obj]
(into #{}
(mapcat
(fn [[k v]]
(let [path (conj prefix k)]
(if (map? v)
(entries path v)
[[path v]]))))
obj)))
You could do this with an explicit stack, too, I'm sure. For the size of
data you're suggesting it doesn't seem to matter much -- and I'm sure
someone clever could turn this into a TCO-able version too :)
