Just restart your kernel if you think something spooky related to state is occurring. This is the number one criticism I see of notebooks, but it is so easy to deal with if you are aware of it. The benefits of being able to rerun an isolated part of your code far outweigh the harms IMO.
Maybe I am misunderstanding how the system works but I don't actually want that kind of Excel-like eager behavior like 90% of the time. Sure it's neat for simple computations but some cells take hours to run in my workflow.
Give me an indicator that a cell is stale but I don't want eager execution on all the time.
