It's interesting to see the "why not Rust?" discussions around the TypeScript news that they're using Go. It shows that Rust has reached a level of maturity that it's a default for some users.
Go does seem to be in a sweet spot for AOT languages with GC though.

When writing long-lived programs (daemons etc) in Rust, I find myself asking *where* I should put data.
In a GC'd language it's just "I have a string" but Rust forces me to find somewhere to put it.
You do get a performance benefit for this work though.
Coming from JS or Python, imports in Rust feel weird. They're entirely optional aliases for fully qualified symbols, which are always available.
I don't know of many other languages where you can just start using libraries. Java is the only one I can think of.
I've just squeezed another 5% of performance out of difftastic by finding a few HashSet values that weren't FxHashSet.
I do wonder whether hash DoS resistance is a good default. Sure, Rust programs are often pretty fast anyway, but it feels like a different threat model to the rest of Rust.
