[沒有翻譯] References Revisited

A reference is fundamentally just a number that is the start position of some bytes in memory. Its only purpose is to represent the concept of where data of a specific type exists. What makes a reference different from just a number is that Rust will validate the lifetime of references doesn't last longer than what it refers to (otherwise we'd get an error when we used it!).
