Re: reduce-kv doesn't reduce a sorted-map in order
Sounds like a bug to me, in that it doesn't behave as I would expect.

Hi,
It seems reduce-kv doesn't reduce a sorted-map in the correct order.
Example -
user (def *sm (into (sorted-map) {:aa 1 :zz 2 :bb 3 :yy 4 :cc 5 :xx 6}))
;= #'user/*sm
user *sm
;= {:aa 1, :bb 3, :cc 5, :xx 6, :yy 4, :zz 2}
;; plain reduce
user (reduce (fn [ret e] (conj ret e)) [] *sm)
;= [[:aa 1] [:bb 3] [:cc 5] [:xx 6] [:yy 4] [:zz 2]] ; correct
;; reduce-kv
user (reduce-kv (fn [ret k v] (conj ret [k v])) [] *sm)
;= [[:cc 5] [:bb 3] [:aa 1] [:yy 4] [:xx 6] [:zz 2]] ; incorrect
Is this a bug?

Confirmed -- thanks for the report.

Hi,
It seems reduce-kv doesn't reduce a sorted-map in the correct order.
Example -
user (def *sm (into (sorted-map) {:aa 1 :zz 2 :bb 3 :yy 4 :cc 5 :xx 6}))
;= #'user/*sm
user *sm
;= {:aa 1, :bb 3, :cc 5, :xx 6, :yy 4, :zz 2}
;; plain reduce
user (reduce (fn [ret e] (conj ret e)) [] *sm)
;= [[:aa 1] [:bb 3] [:cc 5] [:xx 6] [:yy 4] [:zz 2]] ; correct
;; reduce-kv
user (reduce-kv (fn [ret k v] (conj ret [k v])) [] *sm)
;= [[:cc 5] [:bb 3] [:aa 1] [:yy 4] [:xx 6] [:zz 2]] ; incorrect
