When reading a file with code examples, the IM menu
parses the code in the docstrings and ignores the real
code!

For  a real example, see Twisted's twisted.usage.py, or
try this example:

# module life

"""
for the meaning of life, try this:
    class MyMeaning(life.Meaning):
        def __init__(self, foo):
            self.foo = foo
"""

# real code follows

class Meaning:
    def ferfoo(self):
        if self.foo:
            return self.foo
        else:
            return None
