   #     code_ref    - Code reference, invoked for each file in the tree.

   #                   statinfo  a reference to the stat of the file.

   # NOTE:
   #   Yes, we could have just used File::Find, but since we have to get the
   #   stat anyway, this is actually simpler, as File::Find would have gotten
   #   the stat to figure out the file type and then we would have gotten it
