I'm really new to common Lisp and having some struggles. I'm working on a function that given x, y and an array with the index for vertical value returns NIL if there's any element diagonal from (x y).
Why happen this in sbcl? Maybe a bug?But if change :initform to :The problem disappearsI test this in sbcl 1.4.3 and 1.4.11. In clisp it seems that the problem does not arise.
During my course on lisp programming I used the lispworks IDE trial version, which is a very good IDE but it's still a trial version. I searched for a new IDE. And I saw this video https://www.youtube.com/watch?v=VnWVu8VVDbI.
