I'm working through the 4clojure (http://4clojure.com) problem set, here are the answers that I've come up with so far.
Do NOT consider any of these answers as the "right" way to do these, they just pass the 4clojure tests.
I'm new to clojure as I work through these and there's likely a much better/more idiomatic way of doing almost everything.
