You'll want something like this:
myFork :: StateT MyState IO () -> MyState -> StateT MyState IO ThreadId myFork action initialState = liftIO (forkIO (evalStateT action initialState))
That's not quite what I'm looking for. I don't want to create a new thread in which to run the monad but rather to be able to create threads from inside the monad (as a result of running the monad).
And that's what this code does. Do you want it to automatically use the state of the monad ?
myFork :: StateT MyState IO () -> MyState -> StateT MyState IO ThreadId myFork action = liftIO . forkIO . evalStateT action =<< get
keep in mind that nothing the thread will do will affect the state of the main thread. -- Jedaï
