I see that Larry O'Brien is all excited about AOP - specifically, about being able to wrap methods:
Aspects are classes whose methods are injected into existing programs at "join points," the most common of which are method entry and exit. Another way to put it is that aspects intercept method invocations and surround the existing method with new behavior. The other critical feature of aspects is that they do this without any modification of the existing source code whatsoever.
I love the way people using Java and .NET get all excited over things that were invented eons ago in Smalltalk (or in many cases, in Lisp). Take a look at this paper from John Brant, Don Roberts, and Ralph Johnson. That dates to the mid 90's, but if you look at the references at the bottom, you'll see that it's all based on previous work.
The excitement never ends for curly brace programmers, because the past simply doesn't exist...
