Cool. On a side note, I think the old Jupytext extension is hugely underrated. It lets Jupyter run a .py file (with markdown notes as comment in the file, displayed as notes in the web page). Both of these solve the most important part of this problems in iPython - horrible git interaction, horrible programming practice to discouraging writing library files, though Jupyter fixes most of the weird non-deterministic behaviour by forcing you to rerun the script every time you load it (rather than reactive techniques). State is OK for power users but it's known to be a massive pain for people who are just learning programming, and an issue in large projects or with interaction. With this new project having reactive updates I think it's definitely going to be great for beginners, or in gnarly projects. I wonder if it runs on pyodide (a cPython compiled to run in the browser, with matplotlib and scipy bundled).
