I am not sure.  You are recreating a package based on 'ocaml-result'
and not using the package 'ocaml4.09-result'.  Or I miss something
about the symbols.

Moreover, my point is: you are using

 once:
    (properties `((ocaml4.09-variant . ,(delay ocaml4.09-result))))
and once:
     `(("ocaml-result" ,(package-with-ocaml4.09 ocaml-result))))))

and it seems easier to only use one form.  Other said, maybe you do
not need the new 'ocaml4.09-result' and '(package-with-ocaml4.09
ocaml-result)' is enough.

Maybe reword the comment: "no test provided by the package"or
something like that.


All the best,
