Yes, it is very difficult. A sensible API for a standard array

of any other language that has what I'd like to see in Haskell. C+

fusion.
I assume you've looked at SAC? http://www.sac-home.org/
Yes. They have it even easier - they don't have polymorphism, they
don't have higher-order functions, they don't have boxing and laziness
and in a sense, they don't even do general-purpose programming, just
scientific algorithms. And they have no existing language to integrate
their stuff with. This is not to imply that their work isn't
interesting and valuable; IMO, it just doesn't really help us when it
comes to designing a Haskell array library.
