| A monad transformer version of the ST monad |
| Warning! This monad transformer should not be used with monads that |
| can contain multiple answers, like the list monad. The reason is that |
| the will be duplicated across the different answers and this cause |
| Bad Things to happen (such as loss of referential transparency). Safe |
| monads include the monads State, Reader, Writer, Maybe and |
| combinations of their corresponding monad transformers. |
