Rust is a far more extensible, growable lang than Elm and Go, so you get much more mileage from the tools it gives you.

That said, the abstraction ceiling is still there though, and can be frustrating at times when you keep bouncing off it like a balloon… 🎈😭

Parametric & bounded polymorphism, ADTs, macros, escaping into unsafe for making primitives (Vec, Box, Rc, etc are libraries, not built-ins)

Equating Rust to Go and Elm is missing a bunch of those things that give you much more room to build domain-specific abstractions.

Alas, it is still pretty hard to go more meta and convert design patterns into libraries. That's what Rust is missing compared to Haskell.

Yeah, that's why I think Elm is on a better footing. But lacking bounded polymorphism of any kind is a pain. And while it offers native…

…libraries, you aren't able to build your own outside of the packages 'blessed' by Evan. Makes it extremely hard for third parties to extend

Rust should not be free from criticism. But a few features result in it being far more extensible than “pretty much there too” suggests.
