Great points. I strongly agree with your first point. Regrettably, I haven't used any language that solves this. (But believe it's possible, and you've demonstrated with one I haven't used). I'm stuck between two lesser evils, not having the ideal solution you found: 1: Rust: Commits the sin you say. 2: Python, Kotlin, C++ etc: Commits a worse sin: Prints lots of words.. (Varying degrees depending on which of these), where I may or may not be able to tell what's wrong, and if I can, I have to pick it out of a text well. Regarding boilerplate: This is one of the things I dislike most about rust. (As an example). I feel like prefixing`#[derive(Clone, Copy, PartialEq)]` on every (non-holding) enum is a flaw. Likewise, the way I use structs almost always results in prefixing each field with `pub`. (Other people use them in a different way, I believe, which doesn't require this)
