+### What it does
+Checks for usage of `_.map_or(None, _)`.
+
+### Why is this bad?
+Readability, this can be written more concisely as
+`_.and_then(_)`.
+
+### Known problems
+The order of the arguments is not in execution order.
+
+### Example
+```
+opt.map_or(None, |a| Some(a + 1));
+```
+
+Use instead:
+```
+opt.and_then(|a| Some(a + 1));
+```
