Well, in my dbf.py Record class you can use the names of fields as the slice arguments, instead of 
having to remember the offsets.  record['full_name':'zip4'] returns a tuple (or a list, I don't 
remember) of about 13 fields -- this is especially useful as that block of fields might not be in 
the same place in each table.
