In scripts, and when using GetTypeInfoByDecl, it is possible to get a global type when asking for a namespaced type (which might not even exist). For example, registering an enum Foo in the global namespace and then calling GetTypeInfoByDecl("Bar::Foo") results in it returning the type of the global Foo.

The following script should throw (several) compiler errors, but it doesn't:

enum SomeEnum {
  X
}

class SomeClass {
}

void Main() {
  Bar::SomeEnum e;
  Bar::SomeClass c;
}
