Subject: [Caml-list] Optional arguments and type annotations
Hello List,

First, let me say I am quite new to labels (I was waiting for the 3.03
release for using them).

I am used to annotate the top-level functions with their types, and I
was surprised to see that I must write the following to make it

#let bump ?(step:int option) (x:int) =
   match step with
     None -> x * 2
   | Some y -> x + y
#val bump : ?step:int -> int -> int = <fun>

and then there is a discrepancy between the "int option" annotation in
the .ml and the "int" in the interface.

This is not a big deal to solve:), but it looks strange to me.

Best regards,
