This cookbook page is focused specifically on the Spreadsheet datatype, which is similar to dataframes, but also has a lot of specific ideas and views I think. It's not something that other languages couldn't implement.
Page could be a long blogpost, but since it's not temporary information, I made it in a form of a cookbook.
I am the author, but I didn't submit it here. I did submit it on lobsters, and someone reposted it to hn it seems.
Just thinking ahead ... does this mean that for next 5 months, any subject related to Ryelang is not really desired on HN? For example, let's say that I integrate a game engine and write a post about that with examples and make a live database backend for the Rye contexts. Is this all still considered incremental releases / follow up?
The whole thing is relatively woolly/porous, the goal is to avoid obvious repetition, not to lock you out of posting about your work on HN.
