what is the meaning of immutability in defrecord ? i am running below code and I can see that the value is changing in defrecord ,

(def p (atom 0))

(defprotocol protocol-1
  (service [this a b] ))

(defprotocol protocol-2
  (plugin [this]))

(defrecord record [desc id name version]
  protocol-1
  (service [this a b]
    (println id " "name " "a " " (reset! version 1)))
  protocol-2
  (plugin [this]
     (println desc)))

(println (. (->record"a" "b" "c" p) service "k" "j"))

The record has an immutable reference to an atom, which is mutable

is there a channel for machine learning and/or neural nets?
