Does a better standard Mutex matter when parking_lot exist? That's infamously one of the examples of things that should just be left out of the standard library and left to an external library, so it can benefit from rapid development and independent releases, instead of relying on the rest of the language to be shipped.

Will this speed up firefox?

Still no async functions in traits. 😥️

Given that Rust releases every 6 weeks, I think this is not actually an issue, and I do think that a mutex is important enough to warrant being a part of the standard library if possible.

Native support will likely take some time because implementing it is hard (for a starter, it depends on GATs, which are not stable yet, but I think there are more issues). What about using the async-trait crate for the time being? It's not ideal (it requires heap allocation due to type erasure for the time being), but it works well enough so that even the compiler suggests its usage.

I have basically given up on async in Rust, it's a lost cause. I really like this blog post about how unnecessary it really is: https://maciej.codes/2022-06-09-local-async.html
Like, how often do you *really* need it? I know there are plenty of valid use cases, but I feel like people overuse it just to avoid entangling the red path/green path too much, or because they have no idea what their threading model is like and don't want to know, which reminds me of how people relied on GC to pretend to not have to care about memory, until Rust showed us a human way to care about memory that doesn't involve pretending it doesn't exist. I kinda learned to segregate async Rust code into as few places as possible and to actually care about what's running where. Unless you're writing a massively parallel server which the likes of Erlang/Elixir would be more appropriate, you usually can do without async.

I miss the standard OOP features, like classes, inheritance, and exceptions.
Don't take me wrong. I'm not saying they're better than the Rust way.
In fact it's undeniable eg: that composition can be better than inheritance and so on.

That said, sometimes the old, boring, not scalable, way of doing things can be easier.
Also, I'm not saying that I want this instead of that. I'd like to have both.
I mean, I want to use Rust more, but maybe it's a little too opinionated for my taste.
It's entirely possibile that I suck at programming.
Or maybe a little bit of both

For my programs, the new std implementation is now faster than parking_lot, plus it lets me remove a bunch of third-party dependencies (faster build times, less bandwidth waste, etc.) It's a pretty nice upgrade!
