I think regex free solution is best for this
(defn last-indexof [s c]
(->> s (filter #(= c %)) count dec)

Your solution worked, about 4x~5x improvement.
Thanks a lot BG.

I would write like this
(defn sum-by-type [coll]
(->> coll
(map (fn [ {v "Value" t "Type" } ] {t (read-string v) }))
(apply (partial merge-with +
If the map is keyword int map, it will be simpler than above
(defn sum-by-type [coll]
(->> coll
(map (fn [ {v :value t :type } ] {t v
