The man has a valid point - 

In general, Python allows you, for an object f,
to write:

f.SomethingNew = 'Whatever the hell you like'

However, when f is a builtin file object,
it barfs on an AttributeError.

So he can't even help himself by setting his
own EOF attribute to False initially, and
to True when he sees an empty string.

Is there a reason for this Bondage style?
