clojure prewalk with select-keys - 


(clojure.walk/prewalk #(if (map? %)                            (select-keys  % [:c])                             %)                       {:a 1 :b [{:c 3} {:d 4}] :c 5}) =>{:c 5}

why find {:c 5} , not {:c 3}? i'm trying write pull out key/value pairs exist form , @ level key specify.

when function called with

{:c 5, :b [{:c 3} {:d 4}], :a 1}

...it returns:

{:c 5}

...thus discarding other keys, including :b branch, not traversed.
