Agreed, but I don;'t understand why you said this.

Agreed.  The initialization to None can have a comment explaining what
the subclass should do.

Ditto for methods: in an abstract base class, the methods should be
defined (so the signature is known) but raise NotImplementedError.

> In urllib2, there are 6 warnings about 2 different attributes. 

How come PyChecker didn't find the other typo there?
