Hello, Vadim!
Vadim:

A generic solution for old OCaml versions (<4.08) has been explained by
Gabriel Scherer in the following blog post:
http://gallium.inria.fr/blog/overriding-submodules/
The idea is to use destructive substitution while including the original
Ipaddr:
http://caml.inria.fr/pub/docs/manual-ocaml-4.01/extn.html#sec234
module Ipaddr = struct
include (Ipaddr : module type of Ipaddr with module Prefix := Ipaddr.Prefix)
...
end
But I guess that the code you posted should work just fine with OCaml >=4.08
thanks to the following change:
https://github.com/ocaml/ocaml/pull/1892
Best regards.
