Wonder if code generation is going to be able to distinguish private APIs that have public visibility in langs that do not support lib or package levels.
Because, up to now, the contract was: The public interface is in the docs, anything else is internal.
@antirez what is your experience in C?

I don't have many opinions formed on the whole topic of AI just yet.
But I believe writing detailed specs for code generation of non-trivial things, like writing good tests, need flight hours. Plus, you need flight hours for validation (at least for now, though some people directly push).

Working to some PR for Redis that is going to be non trivial and completely AI-developed under a strict specification. It's the same kind of spec I write for myself, but if this goes as I hope, instead of working 2 months, I'll have it ready much faster.

Before the internet, your references were local.
Then, you could interact with world-class experts. In IRC, USENET, mailing lists, easy access to the best books, etc. I believe that exposure raised the level.
Now, we are going to have an expert at our fingertips. The level is going to skyrocket.

I'd say I see Claude Code way more mentioned than Codex.

The constants API chapter in my book has RBS signatures.
Annotations as docs are necessary and orthogonal to static vs dynamic typing.
Readers have to know, e.g., constant names come as symbols. You can say that in English or using some standardized notation, but you have to say it.

Let me tell you a bit about the watch I got in Frankfurt.
Sinn has its manufacture there, visiting their shop was obligatory 😀.
Sinn specializes in what we call "tool watches". Timepieces engineered with a practical purpose.
In the case of the U50 I got, diving and seawater are their thing.

Oh, you are the one who gets it. My model retirement house (since I first so it 25 years ago) is the museum-house of the poet Maximilian Voloshin in Crimea. Its biggest room is basically 2-stories high library (with ladders and all) with a panoramic window overlooking the sea 🥲

I would not retire to a beach, but to a library.
Well, it could also be a library in the beach.

New year's getaway to Frankfurt.
Night photo is the opera house, we are going to see Tosca tonight.
Tried also some Sinn divers this morning in the old town boutique. Some are filled with oil and can go 5 km deep (not a typo!). But did not purchase any in the end.

Given a class object `klass`, it is not uncommon to see
klass.to_s
to get its name.
However, that is unnecessarily indirect. If you want the class name, just ask for it!
klass.name
That is more concise/intentional.

I have released Zeitwerk 2.7.4.
It improves the performance of some validation logic. This may be measurable in large apps with ignored directories and lots of autoload paths.
In Gusto's main application (+20 autoloaders, ~2000 autoload paths), the patch saves 800 ms of boot time.
