Subject: Re: (setq car 0) - Functions on Indices From: Erik Naggum <erik@naggum.no> Date: 02 Oct 2002 23:02:10 +0000 Newsgroups: comp.lang.lisp Message-ID: <3242588530612895@naggum.no> * Bill Birch | Paul Graham's web site (www.paulgraham.com) has a neat idea regarding | compounds in Arc. This "neat idea" dates about about 30 years. It is most noted for having been abandoned. Ignorants keep reinventing what they do not understand are bad ideas until they have tried them for a while. The basic idea was to store an array in the function slot of a symbol. | Your views? If you want this, you have closures and local functions and macros. (defun foo (string ...) (macrolet ((string (n) `(char string ,n))) ... (string 42) ... )) This even works when the indexes are in variables. <-- neat idea -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder. Act from faith, and failure makes you blame someone and push harder.
