Oh hi, So here's a bug on SLIME 2008-12-07. Put this in a Lisp Slime buffer: (defmacro rec (name (&rest vars) &body body) `(labels ((,name ,(mapcar #'car vars) ,@body)) (let* ,vars (,name ,@(mapcar #'car vars))))) Then position your cursor before ",@(mapcar" and type any letter. SLDB appears and reappears again and again and again. -- You only have power over people so long as you don’t take everything away from them. But when you’ve robbed a man of everything he’s no longer in your power — he’s free again. -- Aleksandr Isayevich Solzhenitsyn
