The array literals should really be fixed :-p  But you're right--I 
forgot about closures.  Library functions... that's at least something 
easily addressable by the user.  In all fairness, I agree that it isn't 
terribly practical to forego a GC in D, but it is possible for a 
sufficiently motivated user.
