Now I've rewritten it in Zig in one evening, it's drastically easier to understand and it even has more zero-cost features, all of this in less lines than the original macro-ridden code.
I will soon add more comments and safety features, but for now it felt really good to be able to remove all the redundant code without having to recur to hacks.

Unrelated to the language, but at ~41 or 42 minute mark I noticed the pronunciation of 'executable' and it made me really think. He says it in a way that highlights 'exec', which makes a lot of sense, whereas I normally would say it with emphasis on the third syllable. Now I wonder how most programmers say that word...
According to :

He's using the American pronunciation, and yours is likely the UK version. I've always used the UK pronunciation myself and didn't know there was an alternate way to say it until today.
