Chris is asking whether the Python interpreter will choke when cutting 
and pasting an entire multi-line doctest example.  E.g., try cutting and 
pasting the following text into your Python interpreter session::

--------------- 8< --------------------------------
 >>> class Foo:
...     def __init__(self, bar):
...         self._bar = bar
...     def bar(self):
...         return self._bar
...
 >>> foo = Foo('baz')
 >>> foo.bar()
baz
--------------- 8< --------------------------------

$ python
Python 2.2.2 (#1, Feb 24 2003, 19:13:11)

..... # all the rest are horked, too.
