Since the subject of deprecating code comes up here fairly often, I just
created a "Deprecation" page on the swiki, which hopefully summarizes
how deprecating methods and classes is (or should be) handled in Squeak:

Which reminds me, there are some methods lying around in the image which
have been deprecated for at least 2 releases, and should probably be
removed now in 3.9alpha.
