Just wondering aloud about this. I mean should object references
inside the AST nodes just be copied or should the objects be cloned
as well?
What about object references to non-ANTLR types like String etc?
I presume each call to dup()/dupXXX() be considered as making a
separate clone of the object/object-graph so all cloned objects and
cloned referenced objects must be unique across calls.
