--   The default implementation of <a>unfoldr</a> is independent from that

--   Just like <a>drop</a>, <a>drop64</a>, and the variants of those

--   function must be able to support arbitrarily large indices. Consider
--   using <a>index</a> or <a>index64</a>, even if you need to coerce the

-- | Write a string to a handle

-- | Write a string to a handle, followed by a newline
--

--   Depending on the instance, this function might expect the file to be

--   file.
readFile :: StringRWIO s => FilePath -> IO s

-- | Write a string to a file
--   
--   The file is truncated to zero length before writing begins. The

-- | Polymorphic container of a string
--   
--   When operations take place on multiple <a>GenString</a>s, they are
--   first converted to the type <a>GenStringDefault</a>, which are lazy
--   bytestrings, whenever absolutely necessary (which includes testing for
--   equality, appending strings, concatenating lists of strings, empty
--   strings with <a>empty</a>, and unfolding), making them the most
--   efficient type for this polymorphic container.
