I have the following in my emacs-lisp-mode-hook:
   (with-demoted-errors "Error enabling Paredit: %s" (paredit-mode))
Enabling Paredit unconditionally is too invasive; it will also break
file visiting if the file has a syntax error.
Alternatively, bind paredit-override-check-parens-function to e.g.
(lambda (_) t).
