The real answer is Arthur Whitney is a god-like being with coding powers beyond the mortal realm. Seriously though they're a lot of stories of his excellent work if you search for them. He's supposedly working on kOS so you can run kdb+ on bare metal. Tiny, fast code is what he does. Sure it might look incomprehensible, but it is a few pages of code he can store in his brain at once. Aaron Hsu (someone has some links to his HN posts on here) explains this with his compiler which converts APL to GPU code. His entire compiler (which he has worked on for a long time) is a handful of pages. He says something like "there's no need for an abstraction if I can see everything at once". Most programming languages have implementations that are very long...which do you think has less bugs? Steve McConnals Code Complete has a statistic somewhere on bugs per 100 loc. That doesn't leave a lot of room in Arthur's code base (although you could say his code being so terse makes it an apples to oranges comparison I guess).
