   In general, CLOS doesn't try to implement any information hiding.
   SLOT-VALUE, WITH-SLOTS, and WITH-ACCESSORS can be used anywhere (even in
   ordinary functions rather than methods).  As with the rest of Common Lisp,
   the onus is on the programmer to establish and follow programming
   conventions, rather than having them be enforced by the language.

The Common Lisp package system can be used for namespace partitioning
(but is essentially orthogonal to CLOS).  Symbols - including class
names, generic function names, and slot names - typically belong to a
particular package, and cannot be referenced outside that package
except through explicit programmer action such as importation or use
of a package prefix.  Typically, however, Common Lisp programmers
define packages rather sparingly - for example, MY-APPLICATION and
MY-APPLICATION-INTERNALS rather than a package for every class.
