Oh, `set-variable' can also be used to set
local options, as in the below Elisp.
(Actually, it is the only `set-variable' I have
in all my Elisp. I have 238 grep hits for
"setq".)

    (defun toggle-local-var (var)
      (set-variable var (not (symbol-value var)) t) )

    (defun toggle-char-mode ()
      (interactive)
      (toggle-local-var 'column-number-mode) )

    (defun toggle-line-mode ()
      (interactive)
      (toggle-local-var 'line-number-mode) )
