    Quick question: this looks a lot like the "flexible array" mechanism
    which went in around a year ago, and which is documented in
    Documentation/flexible-arrays.txt. I'm not sure we need two of
    these... That said, it appears that there are still no users of
    flexible arrays. If your virtually-indexed arrays provide something
    that flexible arrays don't, perhaps your implementation should replace
    flexible arrays?
