Example usage

> import qualified Z.Data.Vector as V
> import qualified Z.Data.Array as A
>
> -- convert from list
> let v = V.pack [1..10] :: V.PrimVector Int  
> -- vector combinators works on arrays as well
> let a = V.pack [1..10] :: A.Array Int   
> -- slicing vector(slice) is O(1)
> V.take 3 v                              
[1,2,3]
-- slicing array is not O(1)
> V.drop 3 a                              
fromListN 7 [4,5,6,7,8,9,10]

> V.intersperse 10 v

[1,2,3,4,5,6,7,8,9,10,10,10,10,10,10,10,10,10,10]
