> Hi haskellers:
> There is a mistake in http://www.haskell.org/haskellwiki/State_Monad
> It post two functions like this :
> evalState :: State s a -> s -> a
> evalState act = fst $ runState act
> execState :: State s a -> s -> s
> execState act = snd $ runState act
> Both the '$' operators should be '.'.
> Anyone would correct it ?
Well, it's a wiki ... :-)
