In most Smalltalk implementations you probably can't avoid maintaining
your own registry. A big part of Seaside consist of maintaing such
tables: dispatcher to applications, applications to sessions (_s),
sessions to continuations (_k), continuations to callbacks, etc. There
are many named objects, some with random identifiers (WAExternalId),
some with user-defined identifiers, and some are simply numbered.

GemStone is the exception here. Every object has an unique ID by
itself, that can also be used to retrieve that particular object.
