Thanks David. And, to my utter and complete surprise, you actually have a
to implement the getting and setting of a property via the keyword in the
(Get|Set)Property methods, you can't fool it by just putting the keyword
there. I gather it must give a value a round trip through
obj->Set,obj->Get to see whether your (Get|Set)Property methods actually
do as advertised. Very sneaky, actually checking on you like that. Makes
me feel like big brother is watching.
