D doesn't consider null pointer deference to be unsafe, since its 
behavior is predictable (the hardware will catch it and kill the 
program). This btw is arguably wrong, since dereferencing a large 
null object can potentially overwrite other stuff, but it is how 
it is right now.

@safe prohibits casting ints to pointers, doing pointer 
arithmetic, and other similar things that can create hard to find 
bugs and other undefined behavior.
