Well, I am not a library writer yet, but I take it into account. Still a 'few' things to learn. The functions reset-game! and walk! change global variables. So that is correct. The function look only describes the current location, so it does not need the '!'. Just to be absolutely sure: a function that writes to (for example) a log-file does not need the '!'? -- Cecil Westerhof -- You received this message because you are subscribed to the Google Groups "Clojure" group.
