We get extra >>, >>=, \, ->, and "in" tokens, but no new parentheses.
Yes exactly. It's the >>= and >> that gets rid of the parentheses, and reverses the order of the operations. I cant remember where I saw this, but somewhere there is a monad tutorial that starts really from the basics, which is that a "do" list is essentially something like: f (g (h initialvalue ) ) ... which we can rewrite as something like: h initialvalue |> g |> f .. for a suitable definition of |> , something like (off the top of my head, almost certainly wrong): (|>) f g = g f
