ExperTelligence's common lisp produces a bug with the following code. I *believe* that it's a bug but the nuances of common lisp scoping, extent, etc are sometimes confusing. If anyone can provide additional insight I would appreciate it. ;a function for summing the results of applying a function ;to each element of a list. (defun sum (fn lst) (apply #'+ (mapcar fn lst))) ;calls sum with a function which multiplies i by the argument (n) (defun test (i) (sum #'(lambda (n) (* i n)) '(1 2 3))) ;call test with 2 (test 2) => error, i is bound to nil inside the unnamed lambda It seems to me that i should be bound to 2. Thanx in advance, Mark Wagner @ BNR
