The code
 generated by `setup` does not depend on `setup.el`, meaning that your
 initialization file can be byte-compiled more efficiently.
 
+Tip
+---
+
+The first element of a `setup` body can but does not have to be a
+name. That can be exploited to use `setup` in your own macros. I have
+this macro in my personal configuration, when I'm only interested in
+modifying user options:
+
+~~~elisp
+(defmacro setc (&rest args)
+  "Customize user options using ARGS like `setq'."
+  (declare (debug setq))
+  `(setup (:option ,@args)))
+~~~
