Just wanted to agree, kudos to better tooling support being an important enabler of AOP (beyond research prototypes, that is). It is not separation of, but cross cutting concerns what is highlighted, i18n, logging, error handling, target platform, etc., all with potential variations. While these commonalities are usually dealt with by throwing them to a library, the interactions of the alternative layers (there will be since they are going to be heavily coupled by the very definition of "cross cutting") is better dealt with, or could potentially hurt less using some version of AOP ideas (EDIT deleted FODA reference).

Right. The main question in our field is whether the term "AOP" is useful or not. The current popular thinking is that it is not very useful, but modularity, as always, is a great concept.
