LWN: Comments on "The Rust 2024 Edition takes shape"

Forward progress on never type

Really happy to see these changes to type inference to support `!`. Glad that the Rust developers were willing to cause a little bit of ergonomic pain when it comes to generic types alongside diverging paths. I think the new behavior better-reflects what is going on in the compiler and illustrates exactly where the old behavior could let unsoundness seep in.

match ergonomics != macros-by-example

Yes, I think you're right; I must have captured the wrong link while going down my list. Thanks for pointing this out.

I believe the linked bug at "tweaked" (https://github.com/rust-lang/rust/issues/131414) is not about declarative macros as implied, but actually about match ergonomics (elision of references and dereferencing in `match` expressions, not specific to macros).

Goals update

It's possibly also worth noting that the goals were actually for 2024H2, despite the title of the original blog post being "Rust project goals for 2024". It seems the Rust project is intending to work on a six-month roadmap, with the next set of goals being for 2025H1.

Yeah, I saw the December update in my RSS feed just after sending this out. That's timing for you.

The December goals update came out yesterday (presumably after the article was originally written), and is probably a better summary of what was accomplished in 2024 than the November update linked in the article.
