Disallow null references in safe code?

[Uranuz]

I'm not sure what to do about null references. One of my ideas is 
that some type of Exception or Throwable object should be thrown 
when accessing null pointer instead of getting SEGFAULT. In this 
way programmer can handle exception at application level, get 
some information about problem and may be sometimes it's possible 
to recover. At the current state OS send SEGFAULT message and I 
can't even get some info where is the source of problem. It's the 
most annoying thing about null references for me.

Of course we can provide some wrapper struct for reference that 
will check reference for null and throw Exception if it's null. 
Another way is provide it at compiler level. The third variant is 
forbid null references somehow at all (currently it's possible 
via wrapper). As I thinking today for me 2nd variant is prefered. 
Providing Error when reading null variable will reduce code bloat.

But it's only my point of view. Since I dont know anything about 
compiler implementation it's interesting to know what do you 
think of this.
