 Per [RFC 401][rfc401], if you have a function declaration `foo`:
 
 ```
+struct S;
+
 // For the purposes of this explanation, all of these
 // different kinds of `fn` declarations are equivalent:
-struct S;
+
 fn foo(x: S) { /* ... */ }
-extern "C" { fn foo(x: S); }
-impl S { fn foo(self) { /* ... */ } }
+extern "C" {
+    fn foo(x: S);
+}
+impl S {
+    fn foo(self) { /* ... */ }
+}
 ```
 
 the type of `foo` is **not** `fn(S)`, as one might expect.

 Here, transmute is being used to convert the types of the fn arguments.
