Hello Andrew, Wednesday, March 26, 2008, 3:37:53 PM, you wrote:
type of your own, you just need to write your own instance". The thing that makes me suspicious of this logic is the absense of an instance for tuples.
Any insights here?
and even insiders :) i've rewrote arrays library to be more uniform using ideas of Simon Marlow and Oleg Kiselyov unboxed arrays implementation uses GHC primitives that fetches/stores array element by its index. these primitives implemented for simple types - from Word8 to Double but nothing more. they use *indexes*, not *byte offsets* which means that you can use them for addressing array of {Word8,Double}, for example i believe that it should be possible to rewrite array machinery using storable class (now it should not have any overheads compared to these primitives). meanwhile i recommend you to use storable array together with Storable instances for tuples -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
