How can a time function exist in functional programming?
...d. Another context is within an atomic transaction, for which we have the STM monad. Yet another context is in the implementation of a procedural algorithm (e.g. Knuth shuffle) as a pure function, for which we have the ST monad. And you can define your own monads too. Monads are a kind of overlo...
