This took me a while to figure out but K/APL code is built on a different value system than most software. Specifically, the goal is to be able to see and operate on the entire program at once. Obviously this only works for programs up to a certain size but that size is larger than you'd expect when abstractions, variable names, and general legibility are sacrificed. I wouldn't write code this way but I can see how someone would find it valuable.
