libxev VS v

It scales to complex examples as well. Retained memory would be handled with its own allocator: for a large data structure like an LRU cache, one would initialize it with a pointer to the allocator, and use that internally to manage the memory.

Blocking (or rather, non-blocking, which is clearly what you meant) IO is a different story. Zig had an async system, but it had problems and got removed a couple point releases ago. There's libxev[0] for evented programs, from Mitchell Hashimoto. It's not mature yet but it offers a good solution to single-threaded concurrency and non-blocking IO.

I don't think Zig is the best choice for multithreaded programs, however, unless they're carefully engineered to share little to no memory (using message passing, for instance). You'd have to take care of locking and atomic ops manually, and unlike memory bugs, Zig doesn't have a lot of built-in support for catching problems with that.

A language with manual memory allocation isn't going to be the language of choice for writing web servers, for pretty obvious reasons. But for an application like squeezing the best performance out of a resource-constrained environment, the tradeoffs start to make sense.

io_uring support is obviously great & excellent, fulfills the "high performance" part well.

i was not expecting "Wasm + WASI" support at all. that's very cool. implementation is wasi_poll.zig (https://github.com/mitchellh/libxev/blob/main/src/backend/wa...). not to be unkind, but this makes me wonder very much if WASI is already missing the mark, if polling is the solution offered.

gotta say, this is some very understandable clean code. further enhancing my sense that i really ought be playing with zig.

Their site is clearly showing the language is in beta. The V documentation also states that autofree is WIP, and to use the GC instead. This isn't a corporate created language, but looks to be a true volunteer open source effort from people around the world.

Their community, in comparison to others, even has their discussions open and open threads for criticism[1]. These

V also has this https://github.com/vlang/v/blob/master/doc/docs.md#embed_fil...

Goroutines was the selling point for me until they decided to introduce telemetry in their toolchain; that was what forced me to stop using Golang as a whole.

About GC, I would say: if you implement C++'s RAII mechanism to replace garbage collection, then I believe this project will have a bright future.

My final question is the following: how `pcz` compares to V language, from a syntax's perspective [1]?

V has the right to exist, have its supporters, and do things its own way. The creator and developers of V, from what I have seen, has always responded well to constructive criticism. Their language has discussions opened at their GitHub, unlike those for various other languages. They even have a thread for what people don't like and want improved about the language[1], again, something many other languages don't have.

A lot of what was going on initially, was coming from obvious competitors, to include being uncivil, inflammatory, and insulting. The initial "criticism" was not so much that, but false accusations of the language being a scam, vaporware, fraud, or didn't really exist. To include attacks and jealousy about its funding and having supporters. This was not any kind of "valid" criticism, that the creator or contributors of the language could reason about.

The "criticism" never died down, but rather after V was open-sourced and established itself on GitHub. The initial series of false accusations could not stand nor could the support it was getting be stopped. So, the rhetoric and targets shifted to whatever could be found to go after on the newly released alpha version of the language and its new website. In that new mix of what was being thrown at it, there were indeed some very valid criticisms, as can be found with any new language.

Constructive and valid criticism, is not the same as insults, trolling, misinformation, rivalry, or false accusations. There is clearly a difference. It's disingenuous to pretend something from one group is the same as the other, or that the intent behind what is being done is not different.
