We (AutoKitteh) took a different approach to provide durable execution at the language level: We are using Temporal as a durable execution engine, but we built a layer on top of it that provides a pure Python experience (JS coming soon). This is done by hooking into the AST and converting functions that might have side effects to Temporal activities. Of course it's deeper than that.

For the user, it's almost transparent. Regular Python code (no decorators) that you can run as Duralbe workflow in our system or as regular Python.

You can look at the open-source, and we have a blog explaining how it's implemented.
