KlongPy and KlongPy + duckDB are wonderful. GREAT job. I think there's a whole world of backprop / ML work that can be done in that style! Given the heritage not surprising that most Klong code is ~= L in k mode! Same with ngn/k . E.g. sigmoid is almost the same (:: for assign in klongpy , : for l/q/k). The autograd work is great!
