This was a really good summary of what Rust feels like in my opinion. I’m still a beginner myself but I recognize what this article is saying very much.

The hacker news comments are as usual very good too:

    Oh yeah, that is really nice, and something fantastic about Go.

    That said, I found that I care about that a lot less now than I used to. With everything running through CI, having a build take a few minutes instead of a few seconds isn’t really a big deal anymore. And for personal things where I used to build small Go binaries, I just use Python, mostly because it’s easier to drop into a REPL than to iterate with Go.

    I like Go in theory, and I hope they fix a lot of the issues I have with it. But given that Go 2 isn’t happening, maybe it won’t. Or maybe they’ll do the Rust editions thing (seems to be the case in that article) so they can fix fundamental issues. IDK. But I’m guessing some of the things I want aren’t happening, like:

    • map[K]V should be concurrency-safe, or at least have a safe counterpart w/o needing an import
    • destructors, or something like Rust’s Drop trait
    • interface{}(T(nil)) == nil - or better yet, no nil at all
    • slices shouldn’t be able to write beyond their bounds (example here)

    Those are pretty fundamental to how Go works, though maybe the last one could be fixed, but it has been there since 1.0 and people have complained since 1.0…

      I haven’t really written any Go but from trying to debug some issues in Go software and looking at the source code it seems to be the kind of garbage language that is write-only and likely most major projects written in it will take a full rewrite if you want to overhaul it for a new major version (as in the kind of major version where the code base changes significantly, not the kind where you just broke some minor API).

        Honestly, I disagree, but I obviously haven’t seen the code in question.

        Go has a lot of really nice things going for it:

        • very simple syntax - you’re not going to miss a bug because of something small
        • obvious error handling - no hidden exceptions to disrupt logic flow - Rust does this well too
        • lots of idioms, so deviations are obvious - e.g. channels for synchronization

        My problem isn’t with normal program flow, but that the syntax is deceptively simple. That complexity lives somewhere, and it’s usually in the quirks of the runtime. So it’s like any other abstraction, if you use it “correctly” (i.e. the way the maintainers intended), you’ll probably be fine, but if you deviate, be ready for surprises. And any sufficiently large project will deviate and run into those surprises.
