  • Having the ability to overload functions or constructors without a million Stuff::with_x variants is something I consider more ergonomic and not unsafe. I know the Rust community prefers explicitness in many places, but explicitness and safety are somewhat orthogonal in language design. I consider e.g. Swift to be a safe and ergonomic/sugared language, that borrows, no pun intended, a lot of ideas from Rust


  • As long as you limit yourself to a subset of modern C++, it’s actually a decent language. Less guardrails than Rust, but more syntactic sugar (think overloading, default parameters, implicit this, implicit reference-taking, implicit conversions). You could argue those are anti-features, but even as someone who really likes Rust, I gotta admit C++ is occasionally more ergonomic.












  • Counterpoint, I believe the Swift syntax strikes a much better balance than Rust in terms of ergonomics and argument labels are awesome for designing fluent APIs. There are things that Rust does better, aside from having a bigger ecosystem, namely the whole borrowing/ownership system, though they’re catching up (noncopyable types and references are coming soon).

    The concerns about ARC are generally a bit overstated, ARC only comes into play with classes, which modern Swift greatly deemphasizes in favor of structs, enums and protocols. Sure, sometimes you need them, especially when interoperating with Objective-C, but Rust has its escape hatches for reference counting too (Rc/RefCell, Arc/Mutex), those are just (intentionally) a bit more verbose.

    In short, Swift encourages a very similar, value-oriented programming style as Rust with a modern type system (generics, associated types etc.), while offering lots of nice syntactic sugar (property wrappers, result builders etc.)
