C++ implementation of Lox interpreter (based on the book Crafting Interpreters by Bob Nystrom)

C++ implementation of Lox (WIP)

I'm reading Crafting Interpreters book by Bob Nystrom and writing Lox interpreter in C++ as I do this (the original code in the book is written in Java and some is in C). It's fun!

Some day I will return to it... Maybe in another language?
