For *purely* Python 3 code, where your audience (readers, maintainers, 
developers etc) are all familiar with, and expect, Python 3 semantics, 
not really. Maybe if you are writing introspection code which explicitly 
works with the class MRO or base-classes, you might prefer to be 
explicit. Otherwise, do whatever you feel best. For quick and dirty 
throw-away code, feel free to leave out the base class.

If there's any chance that the code might be used in Python 2, or copied 
into a Python 2 module, or read by people expecting Python 2 semantics, 
then you ought to be explicit about the base class.
