dear list, i've made a silly mistake and defined starts-with-subseq so that the order or the arguments is the opposite of starts-with: (defun starts-with (object sequence &key (test #'eql) (key #'identity)) (defun ends-with-subseq (sequence suffix &key (test #'eql)) i will correct this mistake if there's no objection, but this will break backward compatibility (there were no releases since the patch was added). please speak up if it's not desirable! -- attila
