Bonjour, ...
Hello, ...
quel est le probleme de ceci ?
What is the problem with the following ?
bash-2.04$ ocaml
Objective Caml version 3.00
# module type T_A = sig
val string_of_a : 'a -> string
end;;
module type T_A = sig val string_of_a : 'a -> string end
# module A : T_A = struct
let string_of_a = string_of_int
end;;
Signature mismatch:
Modules do not match:
sig val string_of_a : int -> string end
is not included in
T_A
Values do not match:
val string_of_a : int -> string
is not included in
val string_of_a : 'a -> string
Amicalement,
Friendly,
Sven LUTHER
