eg. fizzbuzz using for, match:
-> (for ([i (range 1 16)]) (match (list (modulo i 3) (modulo i 5)) [(list 0 0) (displayln "fizzbuzz")] [(list 0 _) (displayln "fizz")] [(list _ 0) (displayln "buzz")] [_ (displayln i)])) 1 2 fizz 4 buzz fizz 7 8 fizz buzz 11 fizz 13 14 fizzbuzz

-> (for ([i (in-range 1 16)]) (match (list (modulo i 3) (modulo i 5)) [(list 0 0) (displayln "fizzbuzz")] [(list 0 _) (displayln "fizz")] [(list _ 0) (displayln "buzz")] [_ (displayln i)]))
