> In contrast, you can’t really parse a file in Rust...Expanding macros requires name resolution, which, in Rust, is a crate-wide, rather than a file-wide operation...Similarly, the nature of the trait system is such that impl blocks relevant to a particular method call can be found almost anywhere...
matklad doesn't even mention dynamic languages, where perfect name resolution is undecidable. "Fast static analysis, easy static analysis, language designed for static analysis - pick two".
Rust's IDE integration is fast and deep, and I've heard TypeScript's is too, so "easy static analysis" may not be important today. I believe it will as coding evolves due to LLMs, albeit without evidence and I'm not quite sure how.
