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.
