Hello,

why I can't define a recursive vector using Data.Vector, like in the example:

import qualified Data.Vector as V

let fib = 0 `V.cons` (1 `V.cons` V.zipWith (+) fib (V.tail v))

Since I liked to have both element-wise lazy construction and packed data, I created a data-structure for that purpose: http://code.haskell.org/storablevector/Data/StorableVector/Cursor.hs However, those vectors/arrays are finite, but could be extended to a chunky infinite structure.
