Hi, Is it possible to use the Caml OO features to implement
dynamic dispatch (without using type system back doors such as
Obj.Magic or object serialization)? Or are the OO features just
syntax. Thank you, Lex

Dynamic dispatch is the main feature of Ocaml OO.

What do you need dynamic dispatch for? What problem are you trying to
solve?
I ask because I don't think it's possible without Obj.magic and friends.
I've never needed it, but who knows- you might have a legitimate need for
it. In which case your problem becomes a case example and shows me
something important about Ocaml and programming. Or you might just need
to think about the problem differently.
