[Rails-spinoffs] Re: AOP library

[John Beppu]

I get the concept of 'before' and 'after', and I think I understand 'around'.  (It's where you give it a function that does something, then yields to the original function, and when that returns, you run a little bit more code of your own.)

The one thing I'm not sure about is 'introduction'.  What does it mean to add an introduction?
