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. Gr稍e son gameplay innovant et ses fonctionnalit駸 interactives, ce slot promet des parties aussi dynamiques qu’amusantes.
