Language extension / "behavior"
by Didier Verna 25 Jan '23

25 Jan '23

Hello, Section 1.6 Language Extensions of the standard says this: A language extension is any documented implementation-defined behavior of a defined name in this standard that varies from the behavior described in this standard [...] It is unclear to me if the term "behavior" could encompass additional keyword arguments passed to a function or macro. I'm assuming here that the rest of this section is honored (the additional arguments wouldn't alter the confirming code, and their presence is not explicitly prohibited). WDYT? -- Resistance is futile. You will be jazzimilated. Lisp, Jazz, Aïkido: http://www.didierverna.info

Identity of strings
by Andrea Monaco 23 Jan '23

23 Jan '23

ANSI CL allows implementations to copy characters at any time. Does that also applies to strings? I think it should, because strings are made of characters... In particular, I ask if my implementation can evaluate (eq (symbol-name 'aaa) (symbol-name 'aaa)) => nil because it generates the name string at each call to SYMBOL-NAME. Andrea Monaco
