And this is exactly why you do not use shiny new languages for your projects. Hope tigerbeetle won't have too much trouble with this

Andrew’s design decisions in the language have always been impeccable. I’ve never seen him put a foot wrong and would have made the same change myself.
This is also not new to us, Andrew spoke about this at Systems Distributed ‘25.
Also, TigerBeetle has and owns its own IO stack in any event, and we’ve always been careful to use stable language features.
But regardless, it’s in our nature to “do the right thing”, even if that means a bit of change. We call this “Edge” and explicitly hire for people who have the same characteristic, the craftspeople who know how to spot great technical quality, regardless of how young (or old!) a project may be.
Finally, I’ve been in Zig since 2018. I wouldn’t exactly call it “shiny new”. Zig already has the highest quality toolchain and std lib of anything I would use.
Interesting, who designed the old Zig IO stack which alas Andrew needed to replace?
Here is the commit where Reader/Writer was introduced: https://github.com/ziglang/zig/commit/5e212db29cf9e2c06aba36...
This is a few months after `git init`. You can see I was really just working on the parser, with a toy example to get things started.
Over time, I merged contributions that made minor changes and shuffled things around, and these APIs evolved to kind of work okay. But nobody really considered "the Zig IO stack" as a whole and put in design effort. That is happening for the first time right now.
This is how programming languages are constructed. Things evolve slowly over time, and periodically you have to reevaluate things and do major reworkings.
