@cindex CL note---no @code{setf} functions
Common Lisp defines another way to specify the @code{setf} behavior of
a function, namely ``@code{setf} functions'', whose names are lists
@code{(setf @var{name})} rather than symbols. For example,
@code{(defun (setf foo) @dots{})} defines the function that is used
when @code{setf} is applied to @code{foo}. Emacs does not support
this. It is a compile-time error to use @code{setf} on a form that
has not already had an appropriate expansion defined. In Common Lisp,
this is not an error since the function @code{(setf @var{func})} might
be defined later.
