What annoys me about this is that it feels unhygienic. Like in my last article, I’m doing way too much work. The clunkiness of having to match everything against a
Result, only to then re-wrap each output in the correct variant, completely obscures the beauty of that match expression. I mean, seriously, look at it! Not blowing my own horn — I didn’t have to be all that smart to write it — I’m simply pointing out the expressiveness of Rust pattern matching. Even as I was writing this, I was…
