Hi, the following seems to do the trick (?) :
Le 28 mars 10 à 18:38, Dario Teixeira a écrit :
let rec step1 ?story () = match story with
| Some s -> step2 s#title
| None -> step2 "title1"
and step2 title =
let story =
object
method title = title
method count = 0
end
in step3 ~story
and step3 ~story = match story#count with
| 0 ->
- step1 ~story ()
+ step1 ~story:(story :> <title : string>) ()
| 1 ->
let story =
object
method title = "title2"
end
in step1 ~story ()
| _ ->
true
Cheers,
