> Can you suggest something that K does beyond this? I'm not familiar enough with pandas to say for sure that K is way better - but I was familiar enough with numpy back in the day, and that was definitely way too clunky and cumbersome compared to K. But look at e.g. advent-of-code solutions on https://kx.com/2016/01/04/puzzle-solutions-for-advent-of-code/ https://kx.com/2016/01/04/puzzle-solutions-for-advent-of-cod... - I suspect even pandas won't be able to use vector correspondence so succinctly.
