Yes, further reading has led me to believe that Manu is right in 
his request for a virtual keyword (at least). Final by default is 
a great concept on paper, but unless it's possible across Lib 
boundaries (which I'm not sure it is) then to me it does seem a 
bit backwards given that efficiency is a key feature of D and 
most programmers are already used to fixed by default anyways.
