same language. new engine.
The K and Q languages are array programming languages that offer an elegant syntax for high performance operations. In K/Q arrays are the unit of thought. l keeps those languages unchanged but adds transparent compressed vectors as the unit of execution: primitives run directly compressed structures so the full array is never rebuilt. Modern hardware starves for bandwidth long before it runs short of compute — so moving fewer bytes helps make L fast.
