This is a Janet implementation of the Lox programming language, from Crafting Interpreters by Robert Nystrom. It's loosely based on jlox, the Java tree-walking interpreter from the book, but takes advantage of Janet features to simplify the code when possible.

Notably:

• The scanner is a parsing expression grammar
• Scoping is built on top of dynamic bindings
• The repl uses Janet's getline, which wraps linenoise
• While Janet has support for object-oriented programming, most of the code is written in a more functional style. For instance the visitor pattern is replaced by pattern matching
