Further, Go refusing to have macros means that many libraries use reflection instead, which often makes those parts of the Go program perform no better than Python and in some cases worse. Rust can just generate all of that at compile time with macros, and optimize them with LLVM like any other code. Some Go libraries go to enormous lengths to reduce reflection overhead, but that's hard to justify for most things, and hard to maintain even once done. The legendary https://github.com/segmentio/encoding seems to be abandoned now and progress on Go JSON in general seems to have died with https://github.com/go-json-experiment/json .

Many people claiming their projects are IO-bound are just assuming that's the case because most of the time is spent in their input reader. If they actually measured they'd see it's not even saturating a 100Mbps link, let alone 1-100Gbps, so by definition it is not IO-bound. Even if they didn't need more throughput than that, they still could have put those cycles to better use or at worst saved energy. Isn't that what people like to say about Go vs Python, that Go saves energy? Sure, but it still burns a lot more energy than it would if it had macros.

Rust can use state-of-the-art memory allocators like mimalloc, while Go is still stuck on an old fork of tcmalloc, and not just tcmalloc in its original C, but transpiled to Go so it optimizes much less than LLVM would optimize it. (Many people benchmarking them forget to even try substitute allocators in Rust, so they're actually underestimating just how much faster Rust is)

Finally, even Go Generics have failed to improve performance, and in many cases can make it unimaginably worse through -- I kid you not -- global lock contention hidden behind innocent type assertion syntax: https://planetscale.com/blog/generics-can-make-your-go-code-...

It's not even close. There are many reasons Go is a lot slower than Rust and many of them are likely to remain forever. Most of them have not seen meaningful progress in a decade or more. The GC has improved, which is great, but that's not even a factor on the Rust side.

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.
