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 the next figure use specialized lambda lists in some way; see the dictionary entry for each for information about how.

Figure 3-15. Standardized Operators that use Specialized Lambda Lists
A specialized lambda list can contain the lambda list keywords shown in the next figure.

Figure 3-16. Lambda List Keywords used by Specialized Lambda Lists
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.
lambda-list::= ({var | (var [specializer])}*
[&optional {var | (var [init-form [supplied-p-parameter]])}*]
[&rest var]
[&key {var | ({var | (keyword-name var)} [init-form [supplied-p-parameter]])}* [&allow-other-keys]]
[&aux {var | (var [init-form])}*])
