The yarr package
Yarr is a new blazing fast dataflow framework (array library),
mainly intented to process
Storables (including all "primitive" numeric types)
fixed-vectors of them, for example coordinates,
color components, complex numbers.
Yarr framework is inspired by
repa library and inherits its features,
including shape-polymorphism and auto-parallelism.
Additionaly, the framework is polymorphic over type and arity
of fixed-size vectors and supports neat flow operations over them.
For example, you can convert colored image to greyscale like this:
let greyImage = zipElems (\r g b -> 0.21 * r + 0.71 * g + 0.07 * b) image
In some cases the library is considerably faster than

Shortcoming by design: lack of pure indexing interface.
Changes in version 0.9.2:
Safe folds -- see Data.Yarr.Work
Issue with slice-wise loading with unrolled filling function solved
To start with, read documentation in the root module: Data.Yarr.
