+  // WRONG. Semicolons are not required and can be omitted.
+  let mercury = planets[0];
+  let venus = planets[1];
+  let earth = planets[2];
+
+  // WRONG. While you can use semicolons to place multiple statements on a single line,
+  // it is more common and preferred to separate them using newlines instead.
+  let mercury = planets[0]; let venus = planets[1]; let earth = planets[2];
+
+  // RIGHT
+  let mercury = planets[0]
+  let venus = planets[1]
+  let earth = planets[2]
+
+  // WRONG
+  guard let moon = planet.moon else { completion(nil); return }
+
+  // WRONG
+  guard let moon = planet.moon else {
