 Monads are like overloading the semicolon.
 class Monad m where ; (>>=) :: forall a b. m a -> (a -> m b) -> m b ; (>>) :: forall a b. m a -> m b -> m b ; return :: a -> m a ; fail :: String -> m a

+Monads can be used like adapters (the adapter pattern) in OOP.
+A Monad is a class with a private field.
+A monad is just a label that you stick onto a value to tell the compiler it's not a pure functional value.
