I know the Rust Evangelism Strike Force is a meme, but Rust genuinely has a good solution to language rot with its "edition" concept, where the language can be updated and the compiler just converts all code to a mutually-interoperable internal representation. It’s not dissimilar to using something like Babel for JS, except that because this internal representation is extremely simple, it’s far easier for the language to change more, add restrictions, remove restrictions, and so forth, while still being interoperable. Sadly, Rust has no good equivalent when it comes to libraries, and it’s not unheard of to have two libraries that should be interoperable fail to compile because there’s no way to find a single version of a shared library that satisfies both of their version constraints, even though the actual types in question are identical. I’m not sure if the error messages still look like this, but they used to say something like `expected foo::Bar, got foo::Bar`.
