This should work:
# class foo =
object
method bar =
let helper a b ?(c = "") () =
Printf.printf "a = %d; b = %b; c = %s\n" a b c in
helper
end;;
class foo : object method bar : int -> bool -> ?c:string -> unit -> unit end
Any undesired side effects?

method bar ?(baz="moo") () =
(new foo)#bar ~baz ()
end
and the error:
The expression "new foo" has type foo but is used with type
< bar : baz:
