Subject: Polymorphic recursion, please
Date: Thu, 20 Sep 2007 13:51:18 +0200	[thread overview]
Message-ID: <4a708d20709200451p247b08ceodc65f23dd8e2c017@mail.gmail.com> (raw)

Hello,

I've been beaten by lack of polymorphic recursion again. I propose the
following syntax:

let rec (f :> ty) = ...

Here, all type variables (explicit and implicit) in ty are
generalized. The alternative syntax:

let rec (f : 'a b c . ty) = ...

makes it more difficult (if possible? I forgot.) to catch implicit row
variables (I'm using polymorphic variants for subtyping).
