I suspect that You're Doing it Wrong.
You'll see the exception only if you actually try to evaluate the lazy
sequence returned by byte-seq.
(import [java.io InputStream FileInputStream])
(defn byte-seq
[#^java.io.InputStream stream]
(lazy-seq
(let [b (. stream (read))]
(if (>= b 0)
(cons b (byte-seq stream))))))
(defn most []
(with-open [st (FileInputStream. "/home/smithma/.bashrc")]
(drop 5 (byte-seq st))))
(def x (most)) ;; this is OK, it just binds x to the lazy seq
returned by (most)
(first x) ;; not ok, as it tries to get the first element of x, which dies
;; since the file we're reading from is already closed.
