Lisp: Find the setf way of doing the equivalent of fset [closed]

by

(symbol-function 'foo) is a Generalized Variable in elisp, so you can use:

(setf (symbol-function 'forward-word) #'backward-word)

as an alternative to:

(fset 'forward-word #'backward-word)

(As a side-note, you can do the same thing with cl-letf as a replacement for the deprecated flet when you want to override a function using dynamic scope.)
