convert all values in a map that are keyword into nil

(clojure.walk/walk (fn [[k v :as m]] (if (keyword? v) [k nil] m)) identity {:valor 10 :teste :v})

it’s possible to make it work with clojure.walk, here is a Specter solution just for fun:
(def recurse-maps
(recursive-path [] p
(if-path map?
[MAP-VALS p]
STAY)))

user=> (setval [recurse-maps keyword?] nil {:a :b :c 1 :d {:a :b :c 1 :d {:a nil :b :c}}})
{:a nil, :c 1, :d {:a nil, :c 1, :d {:a nil, :b nil}}}

Or using postwalk

  (fn [form]
    (prn form)
    (if (and (map-entry? form) (keyword? (second form)))
      [(first form) nil]
      form))
  {:a 10 :b {:c :to-nil :d 73 :f {:x :bad :y :bad}}})```

No repository file, test, or entry point is identified. Start by locating the relevant map-walking examples or tests, then compare the requested nested-map behavior with the provided clojure.walk, postwalk, and Specter examples; done should include a clear repository location and expected output.
