Correction: the Common Lisp Object System (CLOS) indeed considers
every entity to be an object - i.e, an instance of some class on which
methods can specialize.  Thus, one can specialize a method for
integers, or symbols, or sequences.  It is also true, however, that
CLOS classes differ in their inheritance behavior according to
metaclass (STANDARD-CLASS, STRUCTURE-CLASS, or BUILT-IN-CLASS); and it
is also true that functionality may reside not only in methods but
also in (unspecializable) functions and macros.
