No, it's not an oversight. The implementation is not complete. Just
last week, we have started a second go at a complete implementation of
fast arrays. Don't hold your breath though, it's a lot of work.
The interface of GHC.PArr will not change very much, but it'll use type
classes and associated types in a very essential way. Underneath, a lot
of GHC specific will be used to optimise code, such as rewrite rules.
So, I don't think this is suitable for Haskell'.
