What's the language you're thinking of that has more of these decisions fixed in the standard library? I know it's not Ruby, Python, Rust, or Javascript. Is it Java? I don't think this is something Elixir does better.
You're answering the question of "which languages have UUIDs in their standard libraries" (Javascript is not one of them). That's not the question I'm asking. If you wrote a new Python program today that needed to make HTTP requests, would you rely on the stdlib, or would you pull in a dep? In a Java program, if you were encrypting files or blobs, stdlib or dep?
Is C# the language that gives the Go stdlib a run for its money? I haven't used it much. JS, Python, and Ruby, I have, quite a bit, and I have the sprawling requirements.txts and Gemfiles to prove it.
I asked the question I did upthread because, while there are a lot of colorable arguments about what Go did wrong, a complete and practical standard library where the standard library's functionality is the idiomatic answer to the problems it addresses is one of the things Go happens to do distinctively well. Which makes dunking on it for this UUID thing kind of odd.

For a short script, the standard "urllib.request" module [0] works pretty well, and is usually my first choice since it's always installed. For a larger program, I'll usually use a third-party module with more features/async support though, but I'll only do this if I'm using other third-party dependencies anyways.

I checked the top 10 Go repositories on GitHub [1], and all but 1 of them have 30+ direct dependencies listed in their "go.mod" files (and many more indirect ones). Also, both C and JavaScript are well-known for their terrible standard libraries, yet out of all languages, JavaScript programs tend to use the most dependencies, while C programs tend to use the least. So I don't think that the number of dependencies that an average program in a given language uses says anything about the quality of that language's standard library.
Fair enough, but the quality/breadth of the standard libraries is fairly topic-specific in Go (and all languages, really). There's a reason that you picked networking and crypto for your examples, since the Go standard library is indeed really strong here—I don't even like Go, but if I had to write a program that did lots of cryptography and networking, then Go would probably be my first choice.
But lots of programs (and most of the programs that I write) don't use any cryptography, and only have trivial networking requirements, and outside those areas, I'd argue that the Python standard library [0] has broader coverage, supports more features, and is better documented than the Go standard library [1].
The Go standard library is still pretty great though, and is well ahead of most other languages; I just personally think that it's a little worse than Python's. But if you mostly write networking/crypto code, I can easily see how you'd have the opposite opinion.
I gave that example to refute the point that having worked on projects in other languages with tons of third-party dependencies implies that those languages have poor standard libraries. I certainly didn't intend to imply that that means that Go has a poor standard library or that small Go projects often use hundreds of third-party dependencies like JavaScript projects tend to do.
Go's package management is actually one of its strongest points, so I think that it's unsurprising/good that some projects have lots of dependencies. But I still stand by the point that you shouldn't judge a language based on how many dependencies most programs written in it use.
(Except for JavaScript, where I have no problem judging it by the npm craziness :) )
No one is debating whether Go is missing a uuid package from its standard library; the debate is about whether this is indicative of a general trend with the Go standard library (as the gp claimed above).
If you’re arguing as the grandparent did that Go regularly omits important packages from its standard library, then it’s not unreasonable to ask you for your idea of an exemplary stdlib.
I think the closest thing to an exemplary stdlin is rust's std. I think it strikes a good balance between being too small or too big. Unfortunately, what rust doesn't really have (yet) is a "blessed" set of libraries to supplement the stdlib.
The problems with a big "batteries included" standard library like go or python strives for, are that you will inevitably leave things out that at least some people consider "basic", like uuid, and parts of stdlib will probably have lower quality than third party libraries, like pythons urllib or gos log package, and it is constrained by needing to maintain backwards compatibility and being tied to the language's release cycle.
I didn’t have a strong opinion on standard library sizes until I tried Rust, but Rust was not a very pleasant experience because there were not standard packages or even consistent community advice for things as pervasive as error handling or async.
But I understand people have different opinions and that there will never be a standard library that appeases everyone. I don’t think “having a batteries included library” aims to appease everyone either. But mostly I just don’t understand the people who criticize Go for not having enough things in their standard library because Go’s standard library is one of the more useful (which may not be everyone’s ideal).
My first, and primary, programming language was C# which includes probably too large a standard library. It was definitely a surprise to see how minimal/simple other standard libraries are!
But they're there. I would much rather have a stdlib option which isn't as good as the most popular third party solution, than not have an stdlib option at all. You can't always count on being able to install stuff from pypi, but you can always count on the stdlib being present.
Broadly speaking, maintaining a big std lib is a huge amount of work, so it makes sense that a language team is conservative about adding new surface to a stb lib which they will then have to maintain for a long time.
What would that entail, just a package whitelist? A few renamed packages? In the python 3 transition they renamed urllib2 to just urllib, but now it's almost a dead battery too and you want to use requests.
Honestly the problem was they did not go far enough. They hoped to have a minimal churn switch to avoid getting locked into bikeshedding for the rest of time. However, there was so little user user facing improvements that the required change hardly seemed worth porting. They also failed to initially offer any automatic porting tooling which could have increased adoption.
I will be forever mad that they did not use that as a breaking opportunity to namespace the standard library. Something like: `import std.io` so that other libraries can never conflict.
the idea of what 'batteries included' means has changed a lot in the past twenty years, and like most Go quirks , probably Google just didn't need <missing-things>.
16 random bytes is not a valid UUIDv4. I don’t think it needs to be in the standard library, but implementing the spec yourself is also not the right choice for 99% of cases.
I didn't say about 16 random bytes. But you're almost there. You generate 16 random bytes and perform few bitwise operations to set version and variant bits correctly.
Not that it matters. I don't even think that there's a single piece of software in the world which would actually care about these bits rather than treating the whole byte array as opaque thing.
I think it saves labor and eventual bug hunting to include these in a stdlib. We should not be expected to look up the UUIDv4 spec and make sure you’re following it correctly. This feels like exactly what reasonable encapsulation should be.
I had a similar thought a while back. Looking at the code for existing UUID projects, issues they fixed, and in some cases the CVEs, is a good way to form a different opinion.
Some things are actually hard to implement. I'd spent a lot of time trying to implement concurrent hashmap, for example. UUID is not one of these things.
I was disappointed by Go's poor support for human-focused logging. The log module is so basic that one might as well just use Printf. The slog module technically offers a line-based handler, but getting a traditional format out of it is painful at best, it lacks features that are common elsewhere, and it's somehow significantly slower than the json handler. I can only guess that it was added as an afterthought, by someone who doesn't normally do that kind of logging.
To be fair, I suppose this might make sense if Go is intended only for enterprisey environments. I often do projects outside of those environments, though, so I ended up spending a lot of time on a side quest to build what I expected to be built-in.
I haven't explored enough of the stdlib yet to know what else that I might expect is not there. If you have a wish list, would you care to share it?
What other languages have web socket support or JWT validation as part of their standard libraries?
I don’t disagree with you btw. JWT signing/verification and JWK support is especially something I would prefer had first class implementations. (I’m much less concerned with JWT parsing, which is trivial).

I cannot identify with this at all. We have Python and Go applications in production, and for Go the vibe is mostly "standard library plus a few dependencies" (e.g. SQL driver, opentelemetry) whereas with Python it's mostly "we need a dozen libraries just to get something done".
For example Go has production ready HTTP server and client implementations in the standard library. But with Python, you have to use FastAPI or Flask, and requests or httpx. For SQL there's SQLAlchemy I guess and probably some other alternatives (my Python knowledge is not that great), whereas again with Go the abstraction is just in the standard library and you only include the driver for the specific database.
We use Renovate to manage dependency upgrades. It runs once a week. Every Python project has a handful or more dependency upgrades waiting every week, primarily due to the huge amount of dependencies and transitive dependencies in each project. The Go projects sometimes have one or two, but most of the time they're silent because there is nothing to upgrade (partly due to just having so few dependencies to begin with).
I don't buy this for one moment. Python and breaking changes are lovers. Nobody I have ever worked with builds or tries to build stdlib python. Most Go devs to pride themselves on minimal dependencies.
