2021-01-16 r/2113 feat(tazjin/rlox): Implement variable depth resolverVincent Ambo1-3/+13
Implements the first part of the resolver from https://craftinginterpreters.com/resolving-and-binding.html This is wired up to the execution paths in main, but not yet in the tests. The resolved depth is also not actually used for variable lookups (yet).

2021-01-14 r/2108 feat(tazjin/rlox): Implement early return from functionsVincent Ambo1-0/+17
In the book this is implemented via exceptions as control flow, and I'm sticking somewhat closely to that by doing it via an error variant. Change-Id: I9c7b84d6bb28265ab94021ea681df84f16a53da2 Reviewed-on: https://cl.tvl.fyi/c/depot/+/2395 Reviewed-by: tazjin <mail@tazj.in> Tested-by: BuildkiteCI
2021-01-14 r/2107 refactor(tazjin/rlox): Let scanner tokens own their lexemeVincent Ambo1-89/+89
This removes the runtime dependency on a borrow into the program source code. It's not yet ideal because there are a lot of tokens where we really don't care about the lexeme, but this is what the book does and I am not going to change that.

2021-01-14 r/2106 feat(tazjin/rlox): Implement function definitionsVincent Ambo1-3/+4
... with this, functions now work. Note that this bubbled up another weird code structure nit: The parser::Function type should probably not carry its name directly. However this doesn't matter much and I don't care right now.
