sub FETCH { return undef } works for defined($undef) and
(tied $undef)->{exists} can store out of band properties.
I couldn't get this to round-trip with YAML, I guess special serialization code would be required, either using YAML::Node or some caller() checking kludge in FETCH. Then deserializing would need another hack... nevermind Brad
