// entity for 2 different types). For example:
//
// 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() { }
