Thanks for this article, dolftax! I followed all the examples on my machine with no problem, and I learned some new stuff. I have a question: how difficult is it to implement the ast? It seems like that the bulk of the work for this static code analysis.

For this kind of (read: simple) static analysis, yes, the design and generation of the AST is the dominant factor. For more advanced techniques usually you'd start with an AST directly to not have to deal with parsing and then work on that.

"Crafting Interpreters" by by Bob Nystrom (https://craftinginterpreters.com https://craftinginterpreters.com). Although the book falls short in covering static analysis (obviously), implementation of ast is covered in detail.
