If Gorilla REPL could be launched without an existing project (ideally from the browser rather than the command line), and if new projects could be created from within Gorilla REPL, then many beginners could do everything that they need to do to learn and use Clojure from within Gorilla REPL, without having to learn to use the command line or leiningen or anything else. This would significantly lower the barrier for entry to Clojure programming for total novices.
