L'ajout d'une nouvelle construction en complement du "match" ne me
semble pas indispensable, il peut suffir de rajouter un peu de sucre
syntaxique pour eviter l'ecriture du "when". On peut ainsi preceder
les identificateurs non liants d'un "=" dans le match, en utilisant
camlp4 pour cela.
Le filtrage propose par Caml n'est evidemment pas le seul possible. Il
existe un bon livre de Christian Queinnec sur ce sujet (disponible
gratuitement, voir "Le Filtrage" sur
http://youpou.lip6.fr/queinnec/WWW/Pedagogy.html). La question est de
savoir lequel est le plus adapte a la majorite des programmes, et doit
donc posseder la syntaxe la plus simple...
