# repeat is about _side-effects_, since it returns nil.
# You'll need to use a mutable collection if you want to
# use repeat to add repeated items to a collection:
(var coll @["Y" "Z"]) #=> @["Y" "Z"]
(repeat 3 (array/push coll "A")) #=> nil
coll
# Returns:
@["Y" "Z" "A" "A" "A"]
# You can use map if the whole collection consists
# of these repetitions:
(map (fn [_] "A") (range 3))
# Returns:
@["A" "A" "A"]
