How about this slightly more general interface, which works with the new
FFI libraries, and is trivial to implement on top of the primitives in
hPut :: Storable a => Handle -> a -> IO ()
hGet :: Storable a => Handle -> IO a
Haskell 98 already defines the seek and file size operations to operate
in units of 8-bit bytes, so these don't need to be duplicated. A
version of hGetContents on Storable objects could also be included.
