GvR_says="""
9.3.2 Class Objects

<snip>

class MyClass:
    "A simple example class"
    i = 12345
    def f(x):
        return 'hello world'
then MyClass.i and MyClass.f are valid attribute references, 
returning an integer and a function object, respectively. 
Class attributes can also be assigned to, so you can change 
the value of MyClass.i by assignment. __doc__ is also a 
valid attribute that's read-only, returning the docstring 
belonging to the class: "A simple example class").

I think this is not an invitation and not a warning.
Althpough I cannot find anything wrong with class variables
if one knows what she does.
