Not exactly, I think that actually can be done if you use the @Role annotation within class A (although I'm not crazy about that, why should A have to know about how it's going to be used?). What I'm thinking is more along the lines of: private List aObjects; where I then want to populate aObjects with unique instances of A, possibly in a factory method and have each object be properly intercepted.
