Interesting solution. 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
