[Haskell-cafe] Data.Vector with stride

For low-level performance, especially when dealing with images, pixel buffers, camera devices etc, arrays can have a "stride" to align rows to word boundaries. http://en.wikipedia.org/wiki/Stride_of_an_array Data.Vector does not support strides (as mentioned in http://u.arboreus.com/2011/03/how-to-choose-haskell-array-library.html), but it would be nice to have them, especially for Storable vectors and interfacing with C imaging libraries. Is there a particular reason / difficulty that would go against an implementation of a Data.Vector.Storable.Stride and the corresponding generic vector instances?
