[Haskell-cafe] About do notation.

[Magicloud]

Hi,
    As some articles say, do notation is expand to (>>) and (>>=) when 
being compiled.
    So I want to know the details. Like:
main = do
  a <- getArgs
  b <- getLine
  myFunc1 (head a) b
  myFunc2 b (head a)

    I cannot figure out what is the (>>) and (>>=) way of this.

Thanks.
