A possibility is to use the module system and let your instance
variable and the corresponding accessor method have an abstract type:
this way, you'll still be able to call the method outside of the
module, but you won't be able to use its result. This is described
here:
http://caml.inria.fr/pub/docs/manual-ocaml/manual005.html#ss:friends

Of course, one could probably think of more sophisticated interfaces
for the module, where you would for instance export only a class type
where the accessor method
itself is hidden and a constructor function that performs at the same
time a 'new' and a coercion to this class type. I've never played with
that, though.
