I forgot to mention this early, but possibly you could use the ndp array library. There are some people using its UArr type for (non parallel) strict arrays, that support map/fold/zip et al.

This blog post recently,
http://sequence.complete.org/node/371
shows at least one non-developer is using it :)
Roman, what do you think -- are the unlifted, non-parallel arrays usably `beta'?
Yes, they definitely are. UArr uses stream fusion, BTW, so things should fuse sometimes. On a more general note, we plan to put a generally usable UArr-like layer underneath the current standard array types eventually. This would provide all interesting operations as well as fusion. It might take a while (i.e., months) until I get around to doing it, though. Roman
