+### What it does
+Checks for matches with a single arm where an `if let`
+will usually suffice.
+
+### Why is this bad?
+Just readability – `if let` nests less than a `match`.
+
+### Example
+```
+match x {
+    Some(ref foo) => bar(foo),
+    _ => (),
+}
+```
+
+Use instead:
+```
+if let Some(ref foo) = x {
+    bar(foo);
+}
+```
