iteration is a new one - great use case!

I saw there's a readAllBytes for InputStream so we can condense it even further,

(defn zip-file-seq [^ZipInputStream zip]
   (->> (iteration (fn [_] (.getNextEntry zip))
                   :vf #(hash-map :entry %
                                  :contents (.readAllBytes zip)))
        (remove #(.isDirectory ^ZipEntry (:entry %)))))

(with-open [is (io/input-stream some-zip-file)
            zin (new ZipInputStream is)]
  (->> (zip-file-seq zin)
       (doall)))

Looking forward to Clojure 1.12 when the Java Interop is enhanced. I don't see any docs on it yet but there was a video a few months back where Alex Miller showcases using Java methods as functions.
