quick question about unboxed Vectors : 

Is it possible to create an unboxed vector of unboxed vector ? :  

> import qualified Data.Vector.Unboxed as V
> type UnboxedNestedVextor =  V.Vector (V.Vector Int)

Alternatively I would have to use: 

> import qualified Data.Vector.Unboxed as V
> import qualified Data.Vector as VB

type UnboxedNestedVextor =  VB.Vector (V.Vector Int)

Is there a rule of thumb how much quicker Unboxed Vectors are ?

Cheers Phil
