Languages with large ecosystems often develop interoperable languages. Scala, Clojure, F# and Typescript all benefit from compatible packages in the "primary" language.
I think Rust will eventually see these too. What will they look
Writing type params with <> (e.g. List<Int>) seems the most natural to me: probably because I encountered that syntax first.
Between C++, Java and TypeScript I think it's the most common too.
List[Int] seems to be next most common (Scala, Python) but TIL Gleam uses List(Int)!
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.
