Re: [Haskell-cafe] What's the deal with Clean?

gcross:

Oh, that's strange... the type class "UA" is defined twice, once in Data.Array.Vector and once in Data.Array.Vector.UArr; in the first

No, its exported from the former.

module indexU is a separate function with the sources I exhibited, in the second module it is a method of the UA type-class which seems to have O(1) access for most of the defined instances.

That's incredibly confusing...

There's direct and stream-based versions. You can choose which version you need. If you use the stream-based implementations, the compiler will apply the stream fusion optimization to your loops. If you use the direct versions, that won't apply. I'd be happy to talk more about the design of the library, if you like. -- Don
