alt Hacker Newsthe “(super) efficient” is not there yet. Io is still dynamic dispatch with multiple layers of indirection. afaik it’s slower than before.
the upcoming releases are expected to provide a solution to this “dispatch is comptime-known, but still dynamic” problem, and drop the loses in efficiency.

Wow that’s gnarly it’s using dynamic dispatch. I mean I get it, but I thought zig was some sort of performance demon.

The parent seems to be talking about efficient code style, not necessarily performance implementation, as they go on to discuss how it looks.
That is, I think the point was DevX not io performance.
Hmm in the 2025 talk ( https://youtu.be/f30PceqQWko?si=qZESxMaSyt7fYMfz ), Andrew emphasizes that this approach is more efficient than before- even showing compiled assembly iirc. I guess that was a one-off?
