LispForum

Well, I really want to have rss on lispforum (I always miss discussions because I don't check the webpage often). How can I help you with that? I can install phpBB here, try the different plugins and send you a recipe of how to install the best one. Do you think that would be helpful?

I don't think it was too academic. it was not clear to me if you want to understand how apply is defined, to reduce the items in a vector or something else. I wanted to know if APPLY is some kind o...

I had a quick look at the SBCL source and found apply in eval.lisp , line 279 - search for "defun apply". :) Although I don't understand how it can terminate :D It seems to recurse in every case? that's the apply from my version of sbcl (version 1.0.21.11), the part after the t terminates...

I found these rss plugins for phpbb:

Put another way, how could someone write an APPLY-TO-VECTOR function? This would work something like this: (apply-to-vector #'+ (vector 1 2 3 4)) ==> 10 Well it depends on you *really* want. If you just want to do stuff like your example, reduce works with sequences (including vectors): (reduce #'+...

You guys are more than welcome to participate in the lisp-br mailing list:

Although the name says "Brazilian lisp group", I think it would be very cool to have people from other countries as well.
