2021-03-06	r/2273 feat(tazjin/rlox): Implement global variable definition	Vincent Ambo	1	-1/+1
	identifier_str might look a bit overengineered, but we want to reuse this bit of code and it needs a reference to the token from which to pick the identifier. The problem with this is that the token would be owned by self, but the function needs to mutate (the interner), so this implementation is the most straightforward way of acquiring and working with an immutable reference to the token before interning the identifier.

2021-03-02	r/2263 feat(tazjin/rlox): Intern all string constants	Vincent Ambo	1	-1/+21
	This is again a step closer to the book, but there are some notable differences: * Only constants encountered by the compiler are interned, all other string operations (well, concatenation) happen with heap objects. * OpReturn will always ensure that a returned string value is newly heap allocated and does not reference the interner.

2021-03-01	r/2258 feat(tazjin/rlox): Add initial support for strings	Vincent Ambo	1	-0/+1
	... including concatenation. This diverges significantly from the book, as I'm using std::String instead of implementing the book's whole heap object management system. It's possible that Lox in Rust actually doesn't need a GC and the ownership model works just fine.

2021-02-28	r/2251 refactor(tazjin/rlox): Represent VM values as enums	Vincent Ambo	1	-1/+6
	Introduces a new enum which represents the different types of possible values, and modifies the rest of the existing code to wrap/unwrap these enum variants correctly. Notably in the vm module, a new macro has been introduced that makes it possible to encode a type expectation and return a runtime error in case of a type mismatch.

2021-01-17	r/2124 feat(tazjin/rlox): Initial bytecode representation	Vincent Ambo	1	-0/+1
	This is significantly simplified from the version in the book, since I'm using Rust's Vec and not implementing dynamic arrays manually. We'll see if I run into issues with that ...
