Subject: A propos de "this matching case is unused"
Date: Wed, 04 Jun 1997 16:41:57 +0200 [thread overview]
Message-ID: <33957EB5.1BA8@irit.fr> (raw)
N'ayant pas entrevu de message a ce propos je me permet
de poser la question suivante :
Soit le code suivant (stupide soit mais pas pour le typage)
# fun x -> x
# | x -> 1 + x
#;;
La reponse est la suivante :
Toplevel input:
> | x -> 1 + x
> ^
Warning: this matching case is unused.
- : int -> int = <fun>
Ma question est la suivante : pourquoi prendre en compte
cette branche lors du typage, qui de ce fait instancie le
type de 'x' par 'int' ?
