I'm really excited that my assert_matches!() macro is finally stable. I can't believe it's been five years since I added it to (unstable) Rust. Time flies. https://github.com/rust-lang/rust/pull/82770

@Mara it's you?! Omg thank you so much and congrats!
@Mara ooh, thank you! With that and copyable range types it was such a nice release for long awaited quality of life improvements
