Hmm? That is wrong. These functions explicitly work on arbitrarily long
lazy bytestrings, and return the rest of the stream in a pair:

    readInt :: ByteString -> Maybe (Int, ByteString)
    readInteger :: ByteString -> Maybe (Integer, ByteString)

These are the initial parts of a bytestring lexing library, more of
which is appareing in the bytestring-lex package on Hackage.
