[Caml-list] Optional arguments in inherited methods

[John Goerzen <jgoerzen@complete.org>]

Hello,

I have this defined in a base class:

    method private getdata sname oname =  <code here>

In my subclass, I wish to do this:

    method private getdata ?(raw=false) ?(idepth=10) ?extravars sname oname = <code>

The compiler does not seem to like this at all, though I am at a loss to
explain why.  Can someone help me out?

The error I get is:

The method getdata has type
  ?raw:'a -> ?idepth:'b -> ?extravars:'c -> 'd -> 'e -> 'f
  but is expected to have type string -> string -> string

So even stranger is that it doesn't set a type for anything, even though
it has enough information to figure out the type for everything.

Hints?
