Couldn't help noticing that this is close to the Smalltalk community's conventions for abstract classes. In most Smalltalks, there's a fundamental method, high up in the inheritance hierarchy, called ```subclassResponsibility```. So, any "abstract" method which ought to be implemented by a derived class sends ```subclassResponsibility``` to ```self```. If the method is not overridden, and then gets called at runtime, then ```subclassResponsibility``` is called and raises an exception .

I was writing some Python myself and thinking about this, and cobbled together my own variation on ```subclassResponsibility``` in Python. It's much less complicated.

Of course, yours is better at making Python IDE's highlight the problem "out of the box."
