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).

It wasn't that bad, it's just my English: should be "bitten".
