One project I would like to do (but will have to wait until I've finished my degree): a set of guides/articles* on extending programming languages past the toy stage, and implementing features people need to write larger projects, such as:
- Debugging
- Interoperability with native code
- Syntax highlighting/LSP support
- Dependency management**
What kind of tooling do you miss from new/toy programming languages?
* Or, let's call it what it is, Crafting Interpreters fanfiction
** After discussion with a friend, this guide will read "Whatever Cargo does, go do that"
