I'm surprised this isn't even mentionned in 
http://drdobbs.com/blogs/cpp/232601305

I definitively don't think that pushing stuff like that - I'm suspecting 
for ego reasons - ignoring some flaw of the idea is a good way to 
proceed. This even may be armfull for the language on the long run.

With no override keyword, function can just explode on your face for no 
aparent reason in the source code you are lookign at. This isn't an 
issue we should ignore.

This has a pretty simple solution : don't inherit thoses attributes of 
override isn't present.  On the long run, don't allow override without 
override keyword ?
