How to append to a nested list in a Clojure atom? -

i want append value list in clojure atom:

(def thing (atom {:queue '()})) 

i know when it's not atom, can this:

(concat '(1 2) '(3)) 

how can translate swap! command?

note: asked similar question involving maps: using swap merge (append to) nested map in clojure atom?

user=> (def thing (atom {:queue '()})) #'user/thing user=> (swap! thing update-in [:queue] concat (list 1)) {:queue (1)} user=> (swap! thing update-in [:queue] concat (list 2)) {:queue (1 2)} user=> (swap! thing update-in [:queue] concat (list 3)) {:queue (1 2 3)}
