In F#:
> let f x = x + 2;;
val f : int -> int
> let g x = f x;;
val g : int -> int
> g 10;;
val it : int = 12
> let f x = x + 3;;
val f : int -> int
> g 10;;
val it : int = 12
In Clojure:
(defn f [x]
(+ x 2))
(defn g [x]
(f x))
(g 10) ;; => 12
(defn f [x]
(+ x 3))
(g 10) ;; => 13
Note that in Clojure the most recent version of f gets called in the last line. In F# however still the old version of f is called. Why is this?
