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.

A specialized lambda list can contain the lambda list keywords shown in Figure 3-16.

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.
