Hi Mike,
What I did, which may or not be powerful enough for you, was to use classes.
I'm actually hoping that this thread comes up with something better for me to
use:
class type opaque_type =
object(s)
... various methods required of all data items ...
end
type datavalue =
| Int of int
| Float of float
| Opaque of opaque_type
So it is fairly easy to add a new type, or some kind of weird opaque reference.
I haven't really used it much, so I don't know of its limitations.
Kenn
