My understanding of this is that while all of your class 
functions will be virtual by default, the compiler will reduce 
them to non-virtual unless you actually override them, and to 
override by mistake is difficult because you have to specify the 
"override" keyword to avoid a compiler error.

I'd like to see that understanding confirmed as it was only 
implied in here:
http://dlang.org/overview.html

For extra safety you have to specify "final" which would be a 
pain if that's what you want by default, but I'm not so sure it's 
really necessary if the compiler really does optimize virtual 
functions away.

BTW, the red code/green code concept sounds like the most 
promising route towards a generalized solution. I'll try and find 
the time to watch it as well.
