     # D: OBJECTS INSIDE A DATA STRUCTURE
     # Affect objects by using the class name as a key:

DESCRIPTION
  Data type callbacks
    The basic idea is that you provide a callback subroutine for each type
    of data that you wish to affect or collect information from.

    The constructor, "new()", expects a hash with at least one of the
    following keys:

     * normal : used for normal, non-reference data
     * array  : used for array references
     * hash   : used for hash references
     * code   : used for anonymous subroutines (coderefs)
