>packages interacting poorly in hard to diagnose ways That's a problem of uncontrolled mutability and lack of type signatures. It's a common problem in python, ryby, javascript, emacs lisp and many others. Emacs can run Rust, and it could be solved in the future, but i don't know what's going on with the GPL license. Can one make a dynamic module and use for example the tokio library in emacs when tokio is not GPL?
