I want to count the number of opening and closing marks that `(` and `)` .
(defun bracketing-count (region-start region-end)
"Count opening and closing bracketing marks."
(interactive "r")

(let ( count (count-matches "\(" (point) region-end) )
(message "%d" count) )))

But this is giving me
save-excursion: let' bindings can have only one value-form: count-matches, "(", (point), region-end user-error: Minibuffer window is not active`.

Figured out that I needed to enclose the count variable within parentheses.
(let ( (count (count-matches "\(" (point) region-end)) )

(global-set-key (kbd "[") 'skeleton-pair-insert-maybe)
