Also, how could any sane person ever go into the ngn/k source and find the mentioned implementation? https://codeberg.org/ngn/k/src/commit/ddcc17511ff05e1915f59b...
I don't even want to learn k, I want to learn how to handle such C.
I like the quote about how different programming languages give you tools to think in different ways.
I get the impression languages like k are a good example of this. (That C code looks as dense/concise as k).
For a smaller example, try the J Incunabulum[0] various explanations are available [1][2]
It's been discussed here before too.
