Introduction Hi, my name is Lambdebug. I can show you how a Clojure program is executed step by step. With a little trick I’ve learned from Einstein, I can even travel back in time, and show you the steps backwards. It’s easy to meet me. Ask Mr Leiningen to get me from clojars (including :dev-dependencies [[lambdebug "0.3.3"]] in your project.clj) Then just say these sentences to the REPL,
