    Instead of hash-object and unhash-object, why don't we include
    populations?  The implementation can be done in terms of hash and
    unhash object or more primitively, and they seem to constitute the
    most common use of these procedures.

Actually, the major reason that we implemented hashing is to have
generalized two dimensional property tables, for generic operations.
