It’s a bit hard to tell what’s interesting about the language itself.

On the website, the standard library lacks a table of contents, but you can see what it has here:

https://github.com/xs-lang0/xslang.org/tree/main/src/app/doc...

Here's a lot of really nice features in this language (I really like the actor / nursery designs), but a GIL in 2026 feels like a massive weakness

All the copy is entirely generated. I can't find any actual human associated with this thing.

At this point, it doesn't really matter what the language does, because the author and I have mutual respect. There is none.

Perl developers that depend on XS [1] for extending their code's behavior will have a "lovely" time with this lol!

Here's an example https://github.com/adriaandens/XSamples/blob/master/XSamples...

Interesting idea. I've fantasized about doing something similar myself. Like someone else in this thread already said though, looks very generated, unfortunately.

This language, README, website has been written by AI agents.

At one point, the author may have written a fair bit of code by hand (starting with a Crafting Interpreters project, and then adapting it recently using agents?). The commit history is very confusing.

The design of the VM is nearly identical to the clox interpreter in Crafting Interpreters. There's also a bit of Lua inspiration mixed in the instruction encoding.

Who is this language for? Who is the audience, and what does the author intend to convey to them?

There's a ton of features -- are they used consistently? We have function overloading and traits. We have optional type annotations and effects -- the effects are handled with a (fragile) multi-shot continuation implementation (at least copy Leijen or libmprompt! that code is out there, free to use, and robust!)

There are two parallel type inference systems in `src/types`. The type system which the language actually uses is not consistent yet (see e.g. `inference.c`: "recursive type: bind anyways")

With that being said, I'd take the cross platform claims with an extreme grain of salt ...

Initially, the page looked very intriguing and the promises looked every fascinating. A whole DX toolchain in one binary? The binary can run in different systems? Only 3 MB? Then I read the comments here saying its ai slop, I lost all my interest now.
