The argument to `interactive' is optional, so it'd be

  (defun foo2 ()
   (interactive nil c-mode)

in most of the cases, which seemed less than ideal.  But on the other
hand, not introducing a new keyword would perhaps help with reading
comprehension.

Yup.

Hm...  I don't know?  Extending `interactive' may be a better than
introducing a new directive.  Any opinions here?
