This is my attempt at following along to the excellent Crafting Interpreters book.
It's written in Go because I wanted to get better at Go (and because I'm a masochist). For the most part, it's just a direct translation of the Java code from the book into Go, with some slight design adjustments to be more idiomatic.
WARNING: I decided to skip the AST visitor pattern out of laziness, and instead crammed all of the logic within the Expr/Stmt types themselves. In hindsight, this was an awful idea and has led to countless hours wasted untangling spaghetti code; if you are using this code for inspiration, do not copy this particular design choice.
