Date: Tue, 20 Mar 2001 16:02:24 +0100 [thread overview]
Message-ID: <200103201502.QAA27766@ilt.fhg.de> (raw)
Hi,
I have the class definition:
# class myclass ?(n=0) () =
object
val nn = n;
method get_nn = nn
method clone (na: int) = let (mc: myclass) = new myclass ~n:na () in mc;
end;;
that produces the following error message in the toplevel:
Characters 5-153:
The expression "new myclass" has type ?n:int -> unit -> myclass
but is used with type int -> unit -> myclass
Can sombody tell what is wrong with my class definition?
I would be very apprecitative for any help.
With kind regards
Rolf Wester
