I believe (d) is considered the idiomatic way*. Btw, I think the second case may not be written correctly; if the intended logic is that 9.75 should be returned when either amount > 20 or country = "US", the code should look something like this:
(cond (= total 20) 8.75 (or (> amount 20) (= country "US")) 9.75 :else 10.0) *See: http://dev.clojure.org/display/design/Library+Coding+Standards -- You received this message because you are subscribed to the Google Groups "Clojure" group.
