D is quite a bit safer currently than C or C++, but we've been a bit complacent 
about that advantage and are at risk of falling behind.

I am replying to the question about what is the direction D is going. This is 
the direction and the motivation for it. Whether DIP 1025 is the correct move in 
that direction or not is certainly worthy of technical discussion.

BTW, after not having memory corruption bugs for years, I've lost days of work 
in the last couple months looking for the cause of two memory corruption 
problems in DMD. I had grown complacent.
