-"""Doctest for method/function calls.
-
-We're going the use these types for extra testing
-
- >>> from UserList import UserList
- >>> from UserDict import UserDict
-
-We're defining four helper functions
-
- >>> def e(a,b):
- ... print a, b
-
- >>> def f(*a, **k):
- ... print a, test_support.sortdict(k)
-
- >>> def g(x, *y, **z):
- ... print x, y, test_support.sortdict(z)
-
- >>> def h(j=1, a=2, h=3):
- ... print j, a, h
