While working on D53847, I noticed that this test would fail once we started recognizing the types in the modified `export` statement [0]. The tests would fail because Clang would emit a "declaration does not declare anything" diagnostic instead of the expected namespace scope diagnostic. I believe that the test is currently incorrectly passing because Clang doesn't parse the type and therefore doesn't treat the statement as a declaration. My understanding is that the intention of this test case is that it wants to export a `struct` type, which I believe requires a `struct` keyword, even for types with template parameters. With this change, the only error with these two statements should be the namespace scope issue.
