Nice! I'd been vaguely thinking of redoing my nrepl client but I don't
really use clojure these days. Glad to see you're a fan of ocaml too

It is often convenient to have an nrepl client in a non-jvm language -
so far I've written one in ocaml and Meikel Brandmeyer has one in
factor, that I know of. I'd like to get some ideas for a way to test
client compliance in a language agnostic manner - this will be
especially helpful when nrepl.

fields are not handled properly, status doesn't distinguish between
various types of error). I'd like to get it into full compliance so
