Ok, I found a possible problem, if i try to put all together, so write
something like this:
(defn lazy-reader [filename]
(with-open [fl (clojure.java.io/reader filename)]
(loop [bite (.read fl)]
(lazy-seq
(cons (bite) (recur (.read fl)))))))
Obviously doesn't work...
Any suggest of how fix that ?
Error: CompilerException java.lang.UnsupportedOperationException: Can
only recur from tail position, compiling:(NO_SOURCE_PATH:42)
