SystemOrganization is gone
Last updated at 7:59 am UTC on 8 January 2016
Note: The Modules system referred to on this page (and incorporated in 3.3alpha) is no longer part of the mainline Squeak release

Yesterday I created an SO subclass that entirely simulates categories from module structure and names, and that doesn't allow any manipulation of sys categories anymore. So far it just raises notifications when SO modification and other obsolete messages are sent. It works with the browsers which was the crucial part it seemed, it isn't nice yet, and slightly slowish, but browsers need to be redone more properly later. (hg)

My intention was to really deprecate categories altogether, using them alongside modules in the new scheme really becomes confusing, I think it will be better to stop using them and instead stay within the mindset of the module hierarchy. (So what you are trying to do wrt categories may be a detour. Feed me more questions if my intentions are not clear from the rest of this mail.)

I really think categories are made unnecessary by Modules, but I've needed to retain them for now to keep the browsers working. So the category(:) messages would eventually be removed, but today eg. the category: method is a no-op.
