detect of null reference bugs is better than runtime detection of them.


BTW, the following program:

  class C { int a,b; }

  int test() {
    C c;
    return c.b;
  }

When compiled with -O:

  foo.d(6): Error: null dereference in function _D3foo4testFZi

It isn't much, only working on intra-function analysis and only when the optimizer is used, but it's something. It's been in dmd for a long time.
