Given a mutable reference to a PureMT generator, we can make a RandomSource usable in any monad in which the reference can be modified. For example, if x :: TVar PureMT, getRandomWordsFromMTRef x can be used as a RandomSource in IO, STM, or any monad which is an instance of MonadIO. | |||||
| |||||
Similarly, getRandomWordsFromMTState x can be used in any "state" monad in the mtl sense whose state is a PureMT generator. Additionally, the standard mtl state monads have MonadRandom instances which do precisely that, allowing an easy conversion of RVars and other Distribution instances to "pure" random variables. | |||||
