I would like to see the API make a type distinction between text
handles with Char-based operations, and binary handles with Word8-based
operations. (And phase out openBinaryFile, hSetBinaryMode etc.) It's a
vital distinction that often trips people up. Treating binary data as
Chars with a Latin-1 encoding just feels like a kludge.
