In the example in the readme it states that

Set<Class<?>> annotated = 
  reflections.get(TypesAnnotated.with(SomeAnnotation.class));

In 0.10-RC1, it results in a Set<String>, as with() is backed by default QueryFunction<Store, String> with(Class<?>... keys) { return of(keys); }. Not only that, the collection is empty contrary to what was returned in 0.9.12.
