"My other goal is to show developers that C++ and Java kinda suck" -- really?!
That said, my biggest Rust-gripe has been writing recursive / self-referential data structures. Borrow system is just not very convenient for that and you end up restructing the code to be a bit more Rust-friendly.
Also I think they sort of show the value of Java's simpler approach with everything being a reference in terms of writing code quickly. The alternative approach that C++ competitors use relies on a very specific style unlike what production code at say Google uses, with pointers used as sparingly as possible. With everything being a reference it is much easier to work with graphs for instance.
To me Rust goes even further into the C++ direction where it becomes more and more difficult to quickly write code that compiles. With Java I have no issue writing 100 lines and having everything compile the first time around, particularly with an editor like Intellij. With C++ even Clion struggles significantly with producing helpful info, simply due to the complexity of C++.
Anyway don’t have enough time to really eloquently think through all aspects of this. Also I was just kidding about CF rating, you are far better than me obviously.
To put context around my provocative comment earlier: I write C++ professionally. C++ is the right choice for my organization, though for purely historical reasons. In the long run, I think we'd all be better off if Rust or similar languages replaced their predecessors. So my comment came from a place of personal frustration, the same that led me to find Rust in the first place.
The old wording was too negative; I'm just excited to show that contest programming, which one might imagine to be hard to translate, is not only practical but indeed arguably nicer in Rust.
The irony here is astonishing.
I am a frequent commenter on HN and I rather like C++. I acknowledge its shortcomings without resorting to the tribalism that is marring the reputation of the Rust community.
Please don't assume that all of Hacker News has a homogenous perspective on the utility (or lack thereof) of extremely common languages like C++ or Java. I've said this before in threads like this and I'll say it again: one language does not need to win.
Of course they both have tremendous utility, but so too does a 15 sqm house. Doesn't mean it doesn't suck.
