It's definitely a gawker at first sight. For comparison, take a look at this in
progress YAML parser of mine:

https://github.com/xelxebar/dayaml/blob/22d20b335bfc99e8e140fee8ca5e7f5f1320f72d/Y.apln

I swear that I sweat blood on this making it as brutally direct and clear as
possible!

From indirectly knowing the dev, my understanding is that the code is
hand-written. The motivation is basically to decrease the cognitive dissonance
between writing K and writing C. Ideally, you'd want to just write a K
interpreter using K, but that's a whole different can of worms.

The de facto K interpreter, Shakti, is proprietary and expensive, but from
talking to some people on the inside, I gather that it's also written in this
extremely terse style.

Anyway, thanks for reviving this.
