In general, I think Haskell has too many array libraries, with too many APIs. And that doesn't even take account the overuse of unsafe APIs, or the non-integrated type-level safety tricks - if array accesses were properly optimized, there should be a lot less need for the extreme all-or-nothing checks or home-grown alternative special-purpose APIs:

- type-level code for watermarking indices belonging to certain index sets is one step to eliminate index checks, but hasn't been integrated into any of the standard libs - one could also associate index subsets with operations that do not leave the index superset belonging to an array (eg, if min

At least, uvector seems to take multi-element ops more seriously. But with so many people working on sequential and parallel Haskell array libraries, I was hoping for someone to take a big ax and clear out all that sick and half-dead wood, to give a small number of healthy arrays libs room to grow. Would be a lot easier for us poor naive Haskell array users who otherwise tend to get lost in that forrest!-)

+3 The current array situation is unecessarily messy - and I prefer mathematical elegance to ad-hoc mess. (And you think I use Haskell, why exactly?) Of course, it's all very well complaining about it... somebody still has to *do* all this wonderful stuff. :-/
