It took some coaching to get it to use the terse style I prefer, but here’s what 3.5 came up with in a conversation where I first asked about Rust’s support for regular expressions: use regex::Regex; fn strip_suffix_digits(s: &str) -> &str { let re = Regex::new(r"_\d+$").unwrap(); re.replace(s, "").as_ref() } As someone who does not program in Rust I find that quite readable, though I haven’t run it and can’t comment on how it compares outside of LOC. It does depend on the regex crate though.
