Look at temporal.io. It already implements the same idea, but without requiring a new programming language. You can write workflows in Python, Go and Java and soon many other languages. It doesn't even require await/async style programming. You can make a synchronous call which can take a few days to complete without any problems. And in case of any failures the state of all threads and local variables is automatically restored.
