After I've seen a pretty cool demo of clang-modernize 
(http://clang.llvm.org/extra/ModernizerUsage.html), I think the best way 
to attack this and similar problems is to add a class hierarchy 
analyzer: a command-line utility that is fed an entire project and adds 
as many 'final' as possible without changing semantics.

Time has come to migrate such functionality to tools. We keep on telling 
that "nobody uses the tools" but it seems experience contradicts that 
belief.
