Following along with Crafting Interpreters, in Swift.

To Do

To make this language more my own, I'd like to change a few things about Lox.

Language Improvements

• Remove nil
• Remove semicolons
• Remove parentheses from conditionals; require block statement
• Add +=, -=, /=, *= operators
• Remove ability to invoke initializer directly

Refactors

• Rewrite Parser match() calls with pattern matching; look at if-chains!
• Distinguish statement-starting tokens from other tokens?
