There's no usage of an undeclared variable, but the right-hand-side of the second line uses 'i' before *the programmer* initializes it. Yes, the D compiler chooses to automatically initialize it, but by doing so it silently creates a bug every time the programmer intends 'i' to start out as anything other than 0. And it's not easily noticed since 0 is a commonly-used value. (Something like 0xDEADBEEF would at least be an improvement (albeit a small one) since at least that would stand out more and likely fail more spectacularly.)
