My lazy chunks have type ByteString -> Object. Only internally they use
ByteString.unpack to get the list of Word8s to parse them.

My parser is totally my own so I can do anything I wish. Except it is hard for
me to image a parser working on something else than [Word8]. How do I do this?

So how do I get rid of those (:) and W8# that are allocated everywhere on my 
heap?

Thanks for the suggestion for -hd, really useful option!
