Not to take away from anything you’ve done here, you guys have put a lot of great effort into this, but this paradigm is not “new”. It’s a common modeling paradigm in banks and hedge funds at least. I’ve built/worked on frameworks based on exactly this concept at 2 previous firms. Here’s some open source examples of the same concept: pyungo, fn_graph, Loman

Oh this is great! I knew about fn_graph (claimed "new" as we created this before fn_graph, but OS'd afterwards) -- I think we're talking with the author soon. But the others are awesome. I used to work at a hedge fund and I think this way of thinking came pretty naturally to me...

Yep, I heard that when we open sourced Hamilton initially -- it was right around the time there was a "Bank Python" post floating around too. When I chatted with Travis O. at about the same time, he pointed that fact out, but he said something like: "oh cool, you can do column level *and* row level computation. Nice." So I interpreted that some places don't have the flexibility that Hamilton has?

Otherwise yeah, those other libraries use the same concept, but it's interesting to see the very different UXs with them.
