I tried F# programming.

F# code for Fibonacci number.

let fib n =
  let rec fib_iter n a b =
    match n with
      | 0 -> a
      | _ -> fib_iter (n - 1) b (a + b) in
  fib_iter n 0 1;;
    
printfn "%d" (fib 10);;

F# code for a maximum value.

let lst = [3;1;4;1;5;9;2];;

let rec fmax l x =
  match l with
    | [] -> x
    | lh::lt ->
      fmax lt
        (if x > lh then x
         else lh);;

printfn "%d" (fmax lst 0);;

I feel that the expression of F# is more powerful than Scheme.
