Have come up with the following function.  Would this be enough to count the number
oy opening parantheses in a region ?

(defun bracketing-count (region-start region-end)
  "Counts opening and closing bracketing marks.
Interactive functions enable them to be called using `M-x`"
  (interactive "r")  ; gets region start and end

  (message "Counting bracketing marks ...")
  (save-excursion
    (let (count)
      (setq count 0)
      (goto-char region-start)

      (while (and (< (point) region-end)
		  (search-forward "\(" region-end t))
        (setq count (1+ count))) ))))
