   The use cases are the same as those for tuples.  The named factories
   assign meaning to each tuple position and allow for more readable,
   self-documenting code.  Named tuples can also be used to assign field names

+  to tuples returned by the \module{csv} or \module{sqlite3} modules.
+  For example:
 
   \begin{verbatim}
+from itertools import starmap
 import csv
 EmployeeRecord = NamedTuple('EmployeeRecord', 'name age title department paygrade')
-for tup in csv.reader(open("employees.csv", "rb")):
-    print EmployeeRecord(*tup)

+>>> Color = NamedTuple('Color', 'name code')
