### What it does
Checks for `.or(…).unwrap()` calls to Options and Results.

### Why is this bad?
You should use `.unwrap_or(…)` instead for clarity.

### Example
```
// Result
let value = result.or::<Error>(Ok(fallback)).unwrap();

// Option
let value = option.or(Some(fallback)).unwrap();
```
Use instead:
```
// Result
let value = result.unwrap_or(fallback);

// Option
let value = option.unwrap_or(fallback);
```
