Subject: [Caml-list] stacking abstract base classes
Date: Wed, 21 Nov 2001 12:33:43 -0800	[thread overview]
Message-ID: <003201c172cb$cffe4680$ca01a8c0@homebox> (raw)

I'm trying to stack up several abstract base classes, but apparently
that doesn't fit the current type system. Is there another way to do
this :

class virtual a = object
 method virtual x : int
end

class virtual b = object
 inherit a as super
 method x = pred super#x
end

Without getting this:

$ ocamlc /tmp/x.ml
File "/tmp/x.ml", line 7, characters 17-22:
This expression has no method x

(using OCaml 3.02)
