It's also possible to use the package system, which I'll discuss in Chapter 21, to make
it even more obvious that certain slots aren't to be accessed directly, by not exporting the names of the slots.
Classes also inherit slots from their superclasses, but the mechanism
is slightly different. However, to call them standard classes would be even more
confusing since the built-in classes, such as INTEGER
and STRING, are just as standard, if not more so, because they're defined by the lang |
