Corollary: AOP is the enemy of refactoring.

You unwittingly changed one of the (seemingly unused/unnecessary) pointcuts and your aspects aren't firing anymore. While not impossible to track down, these problems are difficult to resolve.

This worries me every time I use AOP, but I mitigate that risk by writing integration tests which assert that the aspects are doing what they are intended to, and also to raise an alarm if somebody unknowningly breaks them.

I am not sure if this was AOP though maybe I'm committing the no true Scottsman fallacy here. Side note: decorators were not present in Python then, so there was no easy way to do the cutpoint thing in a visible way.
