#ModuleAnnotations - Rethinking scope of ElementType.MODULE

[Remi Forax]

The exact semantics of an annotation depends on the annotation itself.

For some annotations on a class like @NonNull, the semantics applies on all the code inside the class. For an annotation like @Table the semantics as an effect on the class only.

So it should not be different for an annotation on a module.
