+// - Since the 'ordinary' namespace includes functions, data, typedefs, ObjC interfaces, the

+//
+// module1.m: @interface Foo @end Foo *x;
+// module2.m: void Foo(int);
+//
+// - Since the unique name spans translation units, static data/functions within a CXTranslationUnit
+// are *not* currently represented by entities. As a result, there will be no entity for the following:
+//
+// module.m: static void Foo() { }
