If there was better support for it in Common Lisp implementations,
I might want to write "modules" like this (perhaps with the aid of
some macros):


    (let (...)             ; private variables

      (labels (...)        ; private functions

        (defun ...)        ; public functions
        ... ))

So the "parent" might be quite large.
