I&#x27;ve no experience with hard realtime systems, so I won&#x27;t debate about that (I&#x27;ll just say I doubt Scala is suitable for that either), but Haskell can be used to write simulators and games.<p>Haskell <i>is</i> currently a practical general purpose language. I don&#x27;t see any evidence Scala is any better at this. Are you speaking from experience?
