A specialized lambda list is used to specialize a method for a particular signature and to describe how arguments matching that signature are received by the method. The defined names in Figure 3–15 use specialized lambda lists in some way; see the dictionary entry for each for information about how.
defmethod | defgeneric |
A specialized lambda list can contain the lambda list keywords shown in Figure 3–16.
&allow-other-keys | &key | &rest |
&aux | &optional |
A specialized lambda list is syntactically the same as an ordinary lambda list except that each required parameter may optionally be associated with a class or object for which that parameter is specialized.

[ &key {var | ({var | (keyword-name var)} [init-form [supplied-p-parameter]])}* [&allow-other-keys ]]
[ &aux {var | (var [init-form])}*] )
