 ## Async blocks
 
-A regular block in Rust (`{ ... }`) groups code together in the source and creates a scope of encapsulation for names. At runtime, the block is executed in order and evaluates to the value of it's last expression (or void (`()`) if there is no trailing expression).
+A regular block (`{ ... }`) groups code together in the source and creates a scope of encapsulation for names. At runtime, the block is executed in order and evaluates to the value of its last expression (or the unit type (`()`) if there is no trailing expression).
 
 Similarly to async functions, an async block is a deferred version of a regular block. An async block scopes code and names together, but at runtime it is not immediately executed and evaluates to a future. To execute the block and obtain the result, it must be `await`ed. E.g.,
