The idea that the way to get started is with a fancy editor and a
fancy ide is just crazy. The way to get started with Clojure is: write
functions, and run them, and be happy. None of that requires any of
the mandated complications that come from sophisticated editing
environments. Now once you

Clooj has that lightweight feel, like DrRacket. It's not intimidating, and

Presumably you would be doing this on a 1.3 branch of your code.

It's not stupid, it's normal :)
In functional programming,
You can also put a commented out example call of the function, like this:
(defn some-magic [spells wizards]
...)
; (some-magic 5 [:gendalf :einstein])
Which is also handy for quick evaluation in the REPL.
Or you can put these example calls in the (automatic) test code.

You can set lein repl as your inferior lisp program via:
M-x describe-variable
inferior-lisp-program
And as long as you start emacs somewhere in your lein project directory (or
M-x cd to it), you'll have all the libraries loaded in your REPL buffer.
