Re:Pyspread – The Most Pythonic Spreadsheet by movpasd on Tuesday May 07, 2024 @10:13AM (#40285697)
One issue with this is that arbitrary Python code can have arbitrary side-effects.

Your suggestion reminds me a lot of fine-grained reactivity like in SolidJS, which makes sense, since spreadsheets basically operate on reactive programming. Some great articles by Ryan Carnatio on the topic.

The side-effects thing comes in if a user puts in some side-effect in a dependent cell, which is equivalent to adding side-effects in a memo in reactive-speak.
