At this point I usually say memory corruption is not an option 
for type safe languages but D doesn't really provide runtime type 
safety guarantees, or does it?

I think in the future (D 4.0 or something) we could seriously 
consider something like proof carrying code etc to take 
memory/type safety to the next level. People interested in this 
will be aware of Google's effort in this direction NaCl (
