====== Macro LAMBDA ====== ====Syntax==== * **lambda** //lambda-list <nowiki>[[</nowiki>declaration''*'' | documentation<nowiki>]]</nowiki> form''*''// → //function// ====Arguments and Values==== * //lambda-list// - an //[[CL:Glossary:ordinary lambda list]]//. * //declaration// - a **[[CL:Symbols:declare]]** //[[CL:Glossary:expression]]//; not evaluated. * //documentation// - a //[[CL:Glossary:string]]//; not evaluated. * //form// - a //[[CL:Glossary:form]]//. * //function// - a //[[CL:Glossary:function]]//. ====Description==== Provides a shorthand notation for a **[[CL:Special Operators:function]]** //[[CL:Glossary:special form]]// involving a //[[CL:Glossary:lambda expression]]// such that: <blockquote> (lambda //lambda-list <nowiki>[[</nowiki>declaration''*'' | documentation<nowiki>]]</nowiki> form''*''//) ≡ ([[CL:Special Operators:function]] ([[CL:Symbols:lambda]] //lambda-list <nowiki>[[</nowiki>declaration''*'' | documentation<nowiki>]]</nowiki> form''*''//)) ≡ #'([[CL:Symbols:lambda]] //lambda-list <nowiki>[[</nowiki>declaration''*'' | documentation<nowiki>]]</nowiki> form''*''//) </blockquote> ====Examples==== <blockquote> ([[CL:Functions:funcall]] (lambda (x) ([[CL:Functions:math-add|+]] x 3)) 4) <r>7</r> </blockquote> ====Side Effects==== None. ====Affected By==== None. ====Exceptional Situations==== None. ====See Also==== **[[CL:Symbols:lambda|Symbol LAMBDA]]** ====Notes==== This macro could be implemented by: <blockquote> ([[CL:Macros:defmacro]] lambda (&whole form &rest bvl-decls-and-body) ([[CL:Symbols:declare]] ([[CL:Declarations:ignore]] bvl-decls-and-body)) `#',form) </blockquote>
