I like this distinction between CLASS and ASPECT in terms of their intentional
interaction with other classes and aspects. one of the main issue, as I
see it, is that  "INTERACTS IN A HIERARCHICAL AND/OR BLOCK  STRUCTURE with
other classes" is relatively well understood whereas "INTERACTS IN A CROSSCUTTING
WAY with other classes" is, at least for me, full of question marks. For
example; Where, when and who is responsible to specify the details of crosscutting
interaction? 
AspectJ and hyper/j have  completely different approaches to address these
