as it turns out, the !! operator (list !! k is more or less the same as list[k]) takes a machine integer, which 354224848179261915075 is not by some margin even in 64-bit world. The index was wrapping round into a negative number, which !! quite rightly got narky about.
still, it's not beyond the realms of possibility that you might want to access an element of a list which is longer than that. Let's call it !!! - it's like !!, but even more emphatic. (!!!) :: (Integral i) => [b] -> i -> b list !!! n = head . snd $ genericSplitAt n list and with that addition, Hubris will happily fill all of memory with an infeasibly large number.
