If the library creator did not use functors or classes to make their design reusable then the only solution for the user is to include all of the implementations they require: module Array = struct include RichardsArray include JonsArray end Given the lack of libraries available for OCaml anyway, this seems like a very minor concern to me. -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e
