Another interesting development in programming language features is Aspect or Multidimensional language support. The idea is that not all programming concerns are compositional or hiearchical in nature as Object Oriented Programming requires. Some Software concerns crosscut many objects. The traditional example is logging designs. The 'concern' logging 'crosscuts' the entire object base. Please take a look at AspectJ for information on a java Aspect Engine.
