Hi Volker,
In the meantime I did something very simple. I just have a step function
taking a maybe state parameter which recurses until the state is nothing.
Then main = step init

I would use the State monad rather than passing the state explicitly. Then the "body of the loop" is of type "m a" rather than "a -> m a", and you can use "sequence . repeat" on it.
