Auto merge of #31931 - Luke-Nukem:master, r=steveklabnik

Refinement of paragraph referenced by [this issue](https://github.com/rust-lang/rust/issues/31927).

The paragraph in question had been adjusted already, but I've made some further clarifications which should help with readability and not leave the reader any `dangling pointers`.

 This is how you generally move from ‘crash on error’ to ‘actually handle the
-error’, by switching from `expect()` to a `match` statement. The `Result`
-returned by `parse()` is an `enum`  like `Ordering`, but in this case, each
-variant has some data associated with it: `Ok` is a success, and `Err` is a
+error’, by switching from `expect()` to a `match` statement. A `Result` is
+returned by `parse()`, this is an `enum`  like `Ordering`, but in this case,
+each variant has some data associated with it: `Ok` is a success, and `Err` is a
 failure. Each contains more information: the successfully parsed integer, or an
-error type. In this case, we `match` on `Ok(num)`, which sets the inner value
-of the `Ok` to the name `num`, and then we  return it on the right-hand
-side. In the `Err` case, we don’t care what kind of error it is, so we
-use `_` instead of a name. This ignores the error, and `continue` causes us

 Now we should be good! Let’s try:
