I won't comment on the difference between haskell and lisp (both
languages I respect), but I will say that you should add a macro or
high order function (depneding on lisp vs. haskell) that is something
like "(with-client (c args-list)  body)", that way you can simplify
the creation/cleanup of clients. Same idea as with-open-file.  You can
do the same with server.

As for your actual question, there is a deriving(Read), but I don't
remember what extensions are needed.
