When the function bodies are complex, you really want them to start off as far to the left as possible, which is why I would start the left bracket on the next line. Also, it allows you to put in comment lines explaining what the function does -- another important thing for complex functions.. > It's unclear (to me at least) what letfn offers you over regular let, > since functions are just values anyway: In my silly example, nothing. But if the functions are mutually recursive, you can't do that with let. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
