You could use type hints and pre/post conditions:
(defn foo
"Gets adjusted pixels or whatever"
[^BufferedImage screen ^Number x ^Number y]
{:post [(foo-map? %)]}
...)
(defn foo-map?
"True if x is a map of maps with pixel colors ..."
[x]
...)
That said, it would be nice if clojure.repl/doc printed type hints and
pre&post conditions. You can however use clojure.repl/source to see
pre&post conditions.
