Setting hook without calling external function

Question

I am changing the default value for fill-column, then hook it for prog-mode. Would be neat to have a way that I can have a single function to do this. Currently add-hook requires a call to an outside function colum-property in order to set it.

(defun colum-property ()
  (setq fill-column 72))

(defun colum-mhook ()
  (add-hook 'prog-mode-hook #'colum-property))

Answer 1

You can call the hook with a lambda function.

(defun colum-mhook ()
  (add-hook 'prog-mode-hook (lambda()(setq fill-column 72))))

As NickD rightly points out, encapsulating the add-hook in a function doesn't seem to help much. You might as well write the add-hook directly in the Emacs initialization file.
