takes a sequence of rows of clojure data and a sequence of fns (keys for example) that produce the columns, and generates an org table
(defn clj->org
[data-rows col-fns]
(doseq [line (map (apply juxt col-fns) data-rows)]
(println (str "|" (clojure.string/join "|" line) "|"))))
;; edit: use print-table, and support col headers
;; I never realized print-table is an org-table!!

command-line scripting with plk & clj

what to write scripts in?

bash?

perl?

python?
why not clojure?

why not?

bash/perl etc pre-installed

unorthodox installation requirements sometimes not worth it

this is actually a pretty good reason not to
