I think there can also be problems simply because the element type is no
longer fixed to Word8 but also not entirely free, but restricted to
Storable. E.g. you cannot simply replace
SV.fromList . List.map f by SV.map f . SV.fromList
because in the second form not only the result type of 'f' must be
Storable, but the input type of 'f' must be Storable, too.
