AFAICT in your case you do want the variable(s) to contain different values
at different times.

`setf` and `setq` are basically the same thing here.
BTW, if you really do want to avoid `setq` (and hence `setf` as well),
you can of course do it, using recursion:
(defun binary-search (value array)
(cl-labels ((loop (low high)
(let ((middle (floor (+ low high) 2)))
(cond ((> (aref array middle) value)
(loop low (1- middle)))
((< (aref array middle) value)
(loop (1+ middle) high))
(t (cl-return middle))))))
(loop 0 (1- (length array)))))
