In summary, if one does not need a dynamic polymorphic variable in
the extra-parser computations, then a discriminating union will be
useful. But it does not serve as a replacement in the case a
dynamic polymorphic variable is needed.
There is no problem with storing a polymorphic pointer in a
variant. I fail to see the point of your comment.
