Unfortunately, the alternative of English prose currently favored by the ANSI X3J13 and ISO committees for the definition of Common Lisp is even less precise than a metacircular interpreter. Thus, while a system of denotational semantics á la Scheme or ML could be developed for Common Lisp, we believe that a carefully fashioned system of metacircular definitions can achieve most of the precision of denotational semantics. Furthermore, a metacircular definition is also more readable and understandable by the average Common Lisp programmer, since it is written in terms he mostly understands. Finally, a metacircular definition for Common Lisp special forms enables us to transparently customize the representation of certain \"built-in\" mechanisms such as function closures, to enable sophisticated systems like \"Portable Common Loops\" to become truly portable.","PeriodicalId":262740,"journal":{"name":"ACM SIGPLAN Lisp Pointers","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116902303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
