Well I'll be damned, even C/C++ knows that uninitialized variables shouldn't 
be used, and yet D doesn't. This is where Walter claims that getting rid of 
that warning improves safety because it prevents people from "shutting the 
compiler up" by changing this:

int i = i + 5;

Into this code which D happily accepts:

int i;
i = i + 5;
