Alright, I see now. It does seem odd though that array literals would carry a
type that lacks any sort of const/read-only/immutable/etc qualifier, but is
still immutable anyway. Just another of D2's improvements I guess.

Out of curiosity, any idea if the lack of a run-time error on windows is due to
windows itself or just something DMD/OPTLINK does differently between the
platforms?
