In this case it is helpful to allow nested defuns.

Most code is developed in build-fix method as Paul Graham has
explained very well.

For making modules, one puts simply a wrapper and want the minimal to
edit and move things around. An auxilary function then gets nested. I
do this often in a language that is lisp under a different label.
