Currently, there is no way to directly extract the Data.Vector.Vector that backs a Data.Parameterized.Vector behind the scenes. The closest thing one can do is Data.Vector.fromList . Data.Parameterized.Vector.toList, but this is not as efficient as it could be.

Now that I look more closely, Data.Parameterized.Context currently offers a toVector :: Assignment f tps -> (forall tp . f tp -> e) -> Vector e, so there's already precedent for this sort of functionality.
