Hi and thanks for the reply.  Getting the SourceLocation doesn't seem
very interesting as I need to reinvoke the method.

However, the JoinPoint Signature is interesting in this respect.  If I
inspect that in two advices, one at call and one at get, I think that
gives me what I need.

Thanks again,
