@hackage PrimitiveArray0.3.0.0

This library provides efficient multidimensional arrays.

In general all operations are (highly) unsafe, no bounds-checking or other sanity-checking is performed. Operations are aimed toward efficiency as much as possible. Goals of the library are to have arrays according to three ideas: immutablemutable arrays, strictlazy arrays, zero-based/lower-bound arrays. Zero-based arrays save one addition on each access if the lower bound or the array is always zero.

We have forked two repa modules: Shape and Index.

Unboxed vectors are available with implementations based on "primitive" and "vector". The "primitive" version is probably obsolete now, as I don't see any slowdowns anymore. If this continues into GHC 7.6.1, I'll remove the old code (This will probably not break user code using Unboxed.Zero).
