Hi,
you wait for five lines. So you have to enter five lines. Enter three more
and the "hung" will go away.
If you want to read an arbitrary number of lines and bail out depending on
some decision you may use a lazy sequence.
(loop [lines (repeatedly read-line)]
(let [line (first lines)]
(when-not (bail-out? line)
...
(recur (next lines)))))
Kind regards
Meikel
