actually 82, you missed a ) at the end.
should be
(map #(str "Happy Birthday " %) (assoc (vec (replicate 4 "To You")) 2
"Dear XXX"))
my other concern is what the article is discussing, namely making this
readable to other people who don't know clojure.
I don't know how readable it is to java people who don't know clojure.
