They're (presumably) refering to "colorblind" functions. (Note that "blind" is apt here: the color isn't visible, but functions still have color and will break in subtle ways if you try to use them as if they don't.[0]) Zig's approach is probably a improvement over bare async/await, but pre-javascript languages already had more of a improvement in the form of not having async/await. Implementing async/await at all makes the language worse unless there's a (preferably provably) universally-applicable way for functions to be (explicitly) generic about whether they're async or not. 0: https://gavinhoward.com/2022/04/i-believe-zig-has-function-colors/ https://gavinhoward.com/2022/04/i-believe-zig-has-function-c...
