(compile 'foo) when foo is a macro? If FOO is already a macro, what should (compile 'foo ...) do? The CLHS says the macro function should be updated, but it's not clear to me what it should be updated to. Apparently Lispworks and SBCL update the macro function with the new definition. ACL, CCL, and Clisp replace the macro function with a function.... 13 Mar 2010 17:34

group without recursion Hi, I am trying to rewrite GROUP from On Lisp without recursion (just as an exercise). My first attempt is below, I am wondering if there is a nicer (more idiomatic, etc) way to do it. (defun group (list n) "Return elements of LIST as a list of lists in groups of N." (check-type n (integer 1)) (let (s... 17 Mar 2010 13:36

need easy benchmarks I'm looking for some benchmarks which I can implement in several lisp dialects, various common lisp implementations as well as hopefully elisp, and SKILL. They should be algorithms which I can verify are getting the right answer and which I'll be able to measure the execution time of. I was thinking of some al... 13 Mar 2010 13:04
