Yup - the goal is simplicity. Robustness is important, but I expect
the web server to take care of that. What I'm really expecting to lose
here is performance.

You mean src/nano_web/core.clj.

And two tools - lein and clojure itself.
So we go from 3, 0, 1 to 6, 4, 2. I'm not sure that qualifies as
simple, but at least there's less boilerplate for the tools than there
is actual source code.
Thanks for the answer.
And, since I forgot, thanks to Meikel Brandmeyer for his earlier
answer as well.
