[Haskell-cafe] Specify array or list size?

[Daniel Carrera]

Hello,

Right now I'm using type declarations like:

f :: Int -> [Int]

So f returns a list of Ints.

Is there a way to tell Haskell that a list or array must have exactly 
(say) 256 elements? I'd love to have Haskell make sure that the array I 
build is the correct size.

Cheers,
Daniel.
