We pack 5 introduces a slew of new static analysis features, including /*#__pure__*/ https://webpack.js.org/blog/2020-10-10-webpack-5-release/ (Every sufficiently advanced dev tool contains an ad-hoc, informally specified compiler?)

Really interesting post on optimising the Rust compiler: https://blog.mozilla.org/nnethercote/2018/06/05/how-to-speed-up-the-rust-compiler-some-more-in-2018/ I love that the author comments that he still finds lifetimes somewhat scary. You can even work on the compiler without needing to master advanced Rust techniques!
