that behaves weird if theres nil in the list: the following is better:

(defn my-reverse [a-seq]
  (loop [out [], updated-seq a-seq]
    (let [[first-element & rest-of-seq] updated-seq]
      (if (empty? updated-seq)
        out  
        (recur (conj (seq out) first-element) rest-of-seq)))))
      ```
