I noticed a typo in Network.URI: [[ hexDigit c | c >= 'A' && c <= 'F' = ord c - ord 'A' + 10 | c >= 'a' && c <= 'F' = ord c - ord 'a' + 10 | otherwise = ord c - ord '0' ]] I think should be: [[ hexDigit c | c >= 'A' && c <= 'F' = ord c - ord 'A' + 10 | c >= 'a' && c <= 'f' = ord c - ord 'a' + 10 | otherwise = ord c - ord '0' ]] (lowercase 'f' in second line) #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
