Note, though, that a fetched property has at least one distinct
limitation as a "smart list" -- it's not dynamic. After the

If the values on which the result change (in this case, whether the
birthYear is changed because someone made a mistake, or you add or
remove People -- should be "Person"?), this is not reflected in the
fetched property unless you refresh the source object.
So there is no way to get the refreshing to be done automagically
when a new People/Person is added/removed, or when the birthYear is
changed?
I have to admit, I would expect there would be an option one could
set, as to whether the property would be cached or not.
