aspect oriented programming

every once in a while i think i might play around with aspect-oriented programming. wikipedia seems to have a good article to get started. i realized from reading about one python implementation (lightweight python aop: aspects.py) that i could use this to make a caching object database that automatically decides whether to compute store objects or recompute them. or maybe i should read the wikipedia page on programming paradigms first, so i don't jump from one rut to another.
