Ok, I was thinking the idea behind this sounded a lot like the M.O. of Aspect-Oriented Programming, and it wasn't until I followed your github link that I saw that it was an "AOP library for JavaScript".
Not to take anything away from Raganwald, but there are other AOP JS projects (meld[1] would be an example).
I'm one of the people behind hexagonal.js. Raganwald's work enabled us to implement one of the main components - the glue code.
