Removing the destructors does not help; I tried that, and I still got the "polymorphic needs virtual destructor".
I think the reasoning is a subclass with an interesting destructor could always be created,
and if that happened then delete of a base class (with "no" destructor) would fail to run the subclass destructor
and that could lead to leaks.

So I did try getting rid of destructors, (including Form, MatchNode, and MatchRule, as well as others in that hierarchy)
and the message did not go away.
