Hi,

First, i cannot understand what this mean and where we can use these expressions;

let a = None

let b = Some 10 what some mean ?

let b=10

let c = Some true

let d = Some "ok"

Second,

how can write this in ocaml

let matchfunction x y z= match x y z with | | with the condition that function has type int->int->int-> int=

thank you
