--- Comment #1 from Ketmar Dark <ketmar at ketmar.no-ip.org> ---
...and, techincally, it shouldn't.

first case (roughly) does: `int i; while (i < s.length) ...` which is perfectly
legal. but second does: `int i = s.length;`, which requires conversion from
`size_t` (of type `ulong` on 64-bit arch) to `int`, which is illegal.

i'd say that first case should be forbidden too, but the seconds case -- in my
opinion -- doesn't require fixing.
