That's a great point (something I just came across in Stroustroup's 4th 
Edition of TC++PL the other day).

'override' and 'final' are both what are described as "contextual keywords" 
due to backward compatibility concerns.

This means it's not safe to use pre-processor macros to expand either of those 
to be empty as they can be used in normal code sections (even though that's 
probably a bad idea at this point).
