How do you do it when you compute a value as part of a loop? We just saw it with binary-search, so let's use that as example. OK, so they use `setf', not `setq' (set function, not set function quote - ?) That's better, really? Not in that sense at least? (defun binary-search (value array) (let ((low 0) (high (1- (length array)))) (cl-do () ((< high low) nil) (let ((middle (floor (+ low high) 2))) (cond ((> (aref array middle) value) (setf high (1- middle))) ((< (aref array middle) value) (setf low (1+ middle))) (t (cl-return middle))))))) -- underground experts united https://dataswamp.org/~incal
