The one I linked to in my previous post also produces code that's fast enough to use in the critical path in low-latency trading systems. As you may know, q's "scalar performance" is not great; similar to Scheme or python due to boxing overhead (as you can see in the linked k.h file below). Also, the fact that q is untyped has a severe impact on its safe use in large and complex projects. (ETA: https://github.com/Morgan-Stanley/hobbes https://github.com/Morgan-Stanley/hobbes)
