The Borrow Checker

This pass has the job of enforcing memory safety. This is a subtle topic. This docs aim to explain both the practice and the theory behind the borrow checker. They start with a high-level overview of how it works, and then proceed to dive into the theoretical background. Finally, they go into detail on some of the more subtle aspects.
