Finishing touches: privacy and commentsYou may have noticed that the slots in the lobby or in globals have their names displayed in a variety of fonts. This is to reflect their intended use.
Any slot in a Self object can be declared as public, private, or otherwise undeclared. The default is undeclared, and these slots' names are in a sans-serif font. Public slots are in a bold, serif font, and private slots are in a light, serif font.
Categories are sorted alphabetically by name. Within a category, parent slots appear before non-parents, and then public slots appear before undeclared slots which appear before private slots.
The distinction between public and private is purely for documentation. Earlier versions of Self enforced privacy (allowing only sends to self to locate private slots) but this scheme was found to be unworkable. We may introduce some kind of enforcement in a later version, if we can decide on a scheme that works in practice.
Having installed our accounts in the global namespace, we should designate the slots as public.
