+### What it does
+Checks for unit (`()`) expressions that can be removed.
+
+### Why is this bad?
+Such expressions add no value, but can make the code
+less readable. Depending on formatting they can make a `break` or `return`
+statement look like a function call.
+
+### Example
+```
+fn return_unit() -> () {
+    ()
+}
+```
+is equivalent to
+```
+fn return_unit() {}
+```
