Re: [Haskell-cafe] do you have to use fix with forkio?

Personally I would not use fix. I don't think it improves readability. -- Lennart 2009/3/5 Daryoush Mehrtash :

In this chat server implementation http://www.haskell.org/haskellwiki/Implement_a_chat_server

forkIO is used with fix as in:

reader <- forkIO $ fix $ \loop -> do

(nr', line) <- readChan chan' when (nr /= nr') $ hPutStrLn hdl line

loop

Do you have to use fix?  Or is there a way to write this with a "let"?
