Only if you turned multi-argument type constructors into single-argument ones taking a tuple, i.e. type definitions like: type t = Bar of int * int must become: type t = Bar of (int * int) -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e _______________________________________________ Caml-list mailing list.
