Subject: [Caml-list] Polymorphic Variants and Objects
Date: Tue, 18 Dec 2001 14:37:19 +0000 [thread overview]
Message-ID: <200112181411.30786@farrand.net> (raw)
Take a look at the following OCaml class type definition:
class type foo =
object
method bar: [ `A | `B ]
end
I want to be able to relax the type of bar so that it can return any variant
tag, rather than being limited to `A or `B.
Is this possible? I tried
class type foo =
object
method bar: [> ]
end
but this is rejected on the grounds that
The method bar has type [> ] where .. is unbound
Any suggestions?
Regards,
Jim
