This is an absolutely important point that should be considered 
the foundation for the argument for final-by-default. Your 
average programmer is NOT going to tag everything as final, and 
the cost of virtual accessors could be tremendous. There's no 
argument for virtual-by-default that is nearly as powerful as 
this.
