Well, firstly, limiting the body of let to one expression doesn't prevent side-effects. Secondly, Clojure is not a pure functional language, and there are plenty of functions in the core API that have side effects, such as swap!, alter, send, etc. Clojure does place an emphasis on avoiding side-effects where possible, but the reason seems more to do with enabling greater concurrency than preserving functional purity. - James -- You received this message because you are subscribed to the Google Groups "Clojure" group.
