-### What it does
-Checks for usage of `_.map(_).flatten(_)` on `Iterator` and `Option`
-
-### Why is this bad?
-Readability, this can be written more concisely as
-`_.flat_map(_)` for `Iterator` or `_.and_then(_)` for `Option`
-
-### Example
-```
-let vec = vec![vec![1]];
-let opt = Some(5);
-
-vec.iter().map(|x| x.iter()).flatten();
-opt.map(|x| Some(x * 2)).flatten();
-```
-
-Use instead:
-```
-vec.iter().flat_map(|x| x.iter());
-opt.and_then(|x| Some(x * 2));
-```
