I'm probably missing something obvious, but how do you store a polymorphic
variant in a field in a record? Before, when I just used a normal variant
type I called "primitive", all I did was
type my_object = { object_data : primitive; (* etc. *) }
Is there a type that means "any polymorphic variant"? Trying to set
type primitive = [ `PTest ]
forces only `PTest to be the value of object_data. How can I allow anything
to be stored there?
Thanks,
