2021-01-14 r/2104 refactor(tazjin/rlox): Thread lifetimes through interpreterVincent Ambo3-48/+59
In order to store a function in the interpreter's representation of a callable, the lifetimes used throughout rlox need to be threaded through properly. This is currently not optimal, for two reasons: * following the design of the book's scanner, the source code slice needs to still be available at runtime. Rust makes this explicit, but it seems unnecessary. * the interpreter's lifetime is now bounded to be smaller than the source's, which means that the REPL no longer persists state between evaluations Both of these can be fixed eventually by diverging the scanner from the book slightly, but right now that's not my priority.
