((match-func [q :guard even?] (+ 1 q) [z] (* 7 z)) 33)
;; 231
What? Why 231?

I started a project with lein new. I had a jar file I needed to include
in this project (a recommended class from a company that has an API that we
are using -- it would be pointless for me to re-write their code, so I
simply grabbed the class they offered and compiled it as a jar). I ended up

(-
(wrap-keyword-params)
(wrap-nested-params)
(wrap-params))

I am no longer a total beginner at Clojure, but I find I still get badly

I wrote a simple app that gets my data out of an old mysql database and
puts it into mongodb. I have this function:
(defn add-this-record-to-mongo [db record item-type]

(println (str item-type))
