[Omake] join function?

[Nick]

Oops I didn't explain clearly what I meant by concatenation.
I apologize.
The following ocaml code explains the join function better than I could.

----------- join.ml begins -----------------
let rec join x y = match x, y with
  | [], _ 
  | _, [] -> []
  | x :: xs, y :: ys -> (x ^ y) :: join xs ys


let _ =
  let result =
    join ["a"; "b"; "c"; "d" ] [ ".x"; ".y"; ".w"; ".z"]
  in
    List.iter print_endline result
------------ join.ml ends -----------------
