| AI-unrelated tangent, but I think it's pertinent to your comment. I come from a heavily Python background, professionally. I spent the entire first decade-and-change of my career using almost exclusively Python; I know it about as well as a person reasonably can (outside of scientific and ML Python, which I just never got interested in, but that's beside the point). A year and a half ago I got a job doing Rust. At a surface level, it's about as far as you can get from Python in terms of ease of readability, but after 18 months I'm really reconsidering some of my points of view on the matter. "Explicit is better than implicit," for example, is something I still strongly agree with, but my definition of "explicit" has shifted a lot in the past year. Seeing which guarantees are provided through mandatory, explicit, strong typing saves a lot of time over tracking down guarantees in MRs while reviewing Python code. If I see a signature as an `Arc<dyn AudioInterface>`, for example, I immediately know that: - It's thread-safe and memory-managed using reference counting (because `Arc` provides those guarantees); - It's a type-erased object but is guaranteed to provide all the functionality from the `AudioInterface` trait (which, let's say, could be a supertrait of `AudioInput` and `AudioOutput` -- so it provides both of those); - It uses runtime dispatching (since it's a `dyn` rather than a generic/`impl T` where `T: AudioInterface`) I can choose to operate on it by reference with all the caveats that entails, or decide to either `Copy` or `Clone` it, depending on whether that's available for that type and if I can stomach the runtime cost. All that to say -- Rust doesn't suck to review, relative to Python, in the long run. At first, yes, holy crap, it's such a huge cliff, and I can appreciate your point of view... but there's something to be said about having all this information surfaced as part of the language's syntax and semantics. Python still has a special place in my heart, and I'd still use it over anything else if Rust isn't an option, but to echo a popular sentiment from other people who've made this migration, I don't know if I can go back to handwaving away whether or not something'll cause an allocation :) |
