Yay! I didn't know about that command (and I really did search before
reporting this bug, no idea how I missed it!). It doesn't work backward
though as far as I can tell:

(let (message "%s" "foobar")|)

M-x delete-pair there does nothing. I was hopeful about
`electric-pair-delete-pair' but it only works if the pair is adjacent.

I guess this is closer to what I wanted:

(defun my/delete-pair ()
  "Call `delete-pair', perhaps also calling `backward-up-list'."
  (interactive)
  (condition-case nil (delete-pair)
    (t (progn (backward-up-list)
              (delete-pair)))))

Anyway, thanks for the response!
