It other words if I copy the example from "(emacs) Directory Variables"
and perhaps use my own variables:

    (dir-locals-set-class-variables 'unwritable-directory
      '((nil . ((fill-column . 78)))))

    (dir-locals-set-directory-class
     "/usr/include/" 'unwritable-directory)

I get this:


Debugger entered--Lisp error: (wrong-number-of-arguments #[(directory
class mtime) [...]
