 Rust has three "realms" in which objects can be allocated: the stack,
 the local heap, and the exchange heap. These realms have corresponding
-pointer types: the borrowed pointer (`&T`), the shared pointer (`@T`),

 repeatedly as we explore the language. Learning the appropriate role
 of each is key to using Rust effectively.
