[Haskell-cafe] Sparse vector operations

Hi all, In a couple of my projects I have needed to perform operations on (very) sparse vectors. I came up with the attached simple module which defines a typeclass and implements instances for simple and nested (Int)Maps. Is this the right way to go about it? Am I reinventing some wheels? Comments welcome.
