Article <1989Dec11.170552.8455@isy.liu.se> by nicwi@isy.liu.se
(Niclas Wiberg) criticizes the interface to function ``retrieve''
used to retrieve persistent object structures (in the support library
class STORABLE).

The criticism is well-taken but the problem does not arise any more with
the current version (2.2), where retrieval is done in two steps: call a
retrieval procedure; then access the retrieved structure through
attribute ``retrieved''. There is also a more flexible and general
facility supporting persistence: the notion of environment.

[It appears that the 2.2 shipment for Mr. Wiberg's institution is
on its way. Please check with your distributor.]
