Is it a good idea for line-seq to close its BufferedReader when there is no more data? Or at least provide an optional parameter that allows/disallows close?
The cleanest solution with respect to lazy sequences is realisation. (with-open [rdr (...)] (doall (line-seq rdr))) Closing the reader when reaching the end of the seq doesn't help, since maybe you never reach the end of the seq? So passing the seq outside of your responsibility means realising it and closing the reader, eg. via the code above. If the seq doesn't leave your area of responsibility you can consume the seq and close the reader explicitely. At least this is my understanding of the current situation. (Note: this also applies to db connections and such...) Sincerely Meikel
