This helps for the case where a match, such as below:
```rust
let foo = match foo {
Some(x) => x,
None => 0
};
```
gets refactored to no longer need the match, but the match keyword has been left accidentally:
```rust
let foo = match foo.unwrap_or(0);
```
This can be hard to spot as the expression grows more complex.
