Why type inference fails in this code

[rouanvd@softwarerealisations.com]

Hi everyone

I am trying to decide what language to use to write a compiler for my own
programming language.
I am leaning towards OCaml, but I don’t want the type system or debugging
tools to be a problem.

I found this code snippet in a post and was wondering why the type
inference messes up with
The following code:

======================================================
type t = MyInt of int | MyFloat of float | MyString of string ;;

let foo printerf = function
  | MyInt i -> printerf string_of_int i
  | MyFloat x -> printerf string_of_float x
  | MyString s -> printerf (fun x -> x) s
;;
======================================================

I have done the same thing in Haskell and it correctly infers the type of
foo.

I read that there are lots of workarounds for the above code snippet, but
I would like to
Know why this code fails and what is the best workaround for this type of
code.

Regards
Rouan.
