Both macros create a block of code in which simple variable names can be used to refer to slots on a particular object.
At the minimum, a slot specifier names the slot,
in which case the slot specifier can be just a name.
On the other hand, :initargs needn't be exclusive--each :
initarg option in a slot specifier creates a
keyword parameter that can be used to initialize the slot; multiple parameters don't
create a conflict, so the new slot specifier contains all the :initargs.
The &key in the parameter list is required to keep the method's parameter list congruent with the generic
function's--the parameter list specified for the INITIALIZE-INSTANCE generic
function includes &key in order to allow individual methods to supply their own keyword parameters but
doesn't require any particular ones. Java in which all the methods of a class must be
defined as part of the class definition. Common Lisp also supports multiple inheritance--a class can have multiple direct superclasses, inheriting
applicable methods and slot specifiers from all of them.
Grâce à son gameplay innovant et ses fonctionnalités interactives, ce slot promet des parties aussi
dynamiques qu’amusantes.
