Building a Lox Interpreter in Julia

Disclaimer: I wrote this blog post. If this were an "Ask HN" post, though, the question would be "What next after reading Crafting Interpreters?" I have only done the tree-walk interpreter half of the book, but I'm already excited to move beyond Lox, and I'm curious to hear what others have done in this situation.

I thought working with the lossless syntax tree was the key to Rust's pin-point precise error messages. How does rust-analyzer get and print the specific point of error if it throws away the non-essential information before that stage? I suppose the position information is stored along with the Error nodes, in the original parsing?

Now we need a cream cheese interpreter and we'll be all set.
