(loop [ret []
lat (seq l)]
(cond
(not lat) ret
(= (first lat) a) (recur ret (next lat))
:else (recur (conj ret (first lat)) (next lat)
Note, h

after you call (recur ...). That is why (recur ...) is not in tail
position.

Hi, I'm going through some Scheme code to learn Clojure. I defined a
function
rember
as
(defn rember [atom l]
(loop [a atom lat l]
(cond
(empty? lat) `()
(= (first lat) a) (rest lat)
:else (cons (first lat) (recur a (rest lat))
