Useful not just for language keywords, but also identifiers given meaning by macros. For example `thiserror` treats fields named "source" as the Error::source() of your error. If your source means something else, instead of fussing with some kind of #[not_source] attribute, just name it r#source.
big fan of the r#<ident> syntax in rust i should use it more

Howdy all. I'm unfortunately not going to be with my employer for much longer due to team relocation. If anyone has any info on roles that would allow me to continue my Rust compiler work (in New York City), they'd be greatly appreciated.

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust.
In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

TypeScript team: rewrites compiler in Go.

Two days later: WIP 5x speedup.

There are probably 4–6 people who, if they had dedicated their 10 years to a different language or hobby, you would not be hearing success stories about Rust.
but what I can say is, I personally sat down one evening and said "I think Rust can be the next great systems programming language" and then dedicated the next ~10 years of my life to making that happen

We’re building a new static type checker for Python, from scratch, in Rust.
From a technical perspective, it’s probably our most ambitious project yet. We’re about 800 PRs deep!
