not easy enough to use

[RanchoCooper]

current when we use aop, we had to define beanFactory/aspect/pointcut, and then handle AddAdvice explicit

I think there should be a solution (feature) be added to aop, so that we can use aop in golang more easily

The purpose for this project is learn golang reflect feature, and currently is prototype stage.

If you have good idea for improve this project, you could give me a PR or have some pseudocode, thanks.
