Hi.

In GHCi ver 6.6, why this happens ?

Prelude Data.ByteString> Data.ByteString.pack $! Prelude.map (`rem` 256) $ [0..511] "*** Exception: divide by zero

It's the use of `rem` on Word8, by the way:

Prelude> (0 `rem` 256) :: Data.Word.Word8 *** Exception: divide by zero

Sorry, I should clarify, think about how to represent: 256 :: Word8 ;-) -- Don
