Not necessarily. It could return a function suitable for inclusion in a hook:

 (defun turn-on (minor-mode-symbol)
     `(lambda () (,minor-mode-symbol t)))

  (add-hook 'foo-mode-hook (turn-on 'some-minor-mode))

Or maybe

  (defun turn-on (&rest minor-mode-symbols)
    `(lambda () ,@(mapcar (lambda (sym) (list sym t))
                          minor-mode-symbols)))

  (add-hook 'foo-mode-hook (turn-on 'foo-minor-mode 'bar-minor-mode))

Excuse the fake lexical scoping hack. turn-on is probably also not the
right name, as (turn-on 'mode) not turning on any mode might be
confusing.
