Hello all,
Something's always bothered me about map and zipWith for ByteString. Why is it
map :: (Word8 - Word8) - ByteString - ByteString
but
zipWith :: (Word8 - Word8 - a) - ByteString - ByteString - [a]
? Obviously they can be transformed into each other with pack/unpack, and as I

Scott: benchmark the two and you'll see why we have both :-)

Carter: we don't have both. We have one function from each category. My
guess is nobody's ever really needed a really fast zipWith ::
(Word8-Word8-Word8) - ByteString - ByteString - ByteString; that's the
only reason I can think of for its omission.

I did use that a couple of times (`xor`ing 2 ByteStrings together), and was
surprised by the omission back then, but IIRC (can't validate now), there's
a specialised zipWith (as proposed) in the module (with some other name,
obviously), which is not exported, but used when you 'pack' the result of
