Variable values are not inherited in Coldmud, period.  All object
variables have a default value of 0.

I do not think it would be "nicer" to have a more baroque variable
lookup system, notwithstanding people's reliance on it in MOO.  As I
pointed out, such a variable lookup system damages encapsulation, and
can be done trivially in-db.
