Some great discussion and insights here thanks everyone. My continued thoughts: since this is a framework for trying to reduce cognitive load, I'm now thinking a pragmatic approach would be to try it out a few times, either as a set of function steps or a set of class steps and see whether one approach falls out as a preferable pattern to default too. Thinking about it, I can see why classes might be a reasonable default, if you don't need the state, it doesn't matter, if you do, you might be tempted to refactor the script which I think detracts from the goal of this framework. If anyone is using this, in python, would be interesting to hear their experience.
