There's really not much happening in CL that can't be achieved in Clojure (or vice versa for that matter). Just grab a library and write your macros to obtain your desired level of brevity/utility. The first thing I did when moving from Arc to Clojure was port over the web service routing along with the html/json generators & parsers. Since then my server code has morphed into a custom unique hybrid, and now when I look at all of these other examples I think ugh, I'll pass thanks.
