Hook variables clearly separate the two ideas. foo-function *is* a customization point and not an implementation detail. That's the difference between using add-function on a foo-function (a customization point) and using advice-add on some function (some implementation detail). > There's also no buffer-local add-function equivalent. Of course there is: (add-function :before-until (local 'next-error-function) #'my-function) -- Stefan
