Swift and Rust both are known for long build times.

Mostly caused by LLVM.

Other equally expressive languages have multiple implementations, including REPLs, with Go like compilation speeds.

So Swift and Rust just need equally LLVM fat free implementations for the developer loop, leaving the LLVM backend for the blazing execution release builds.

LLVM isn't fast, but there are other slow parts of the process unique to Rust [1].
