However, Ocaml does not support defining objects on the fly. The following > let c = new object method f = 1 end in C c is not valid Ocaml. So, in order to define just one value one needs to define an entire class as in the following example. class f_one = object method f = 1 end let res = C (new f_one) BTW, why is something like the above not in the language? It seems only natural to have such a feature since an analogous construct exists for structs. let module C = struct let f = 1 end in C.f Alex ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
