Add listener to "GameObject.SetActive"?

Hello. I'm writing a script that must do things when certain gameObject's "active" state is changed. I could just call some method inside this script instead of "GameObject.SetActive", but i'm curious - is there any way to add listener to GameObject's "SetActive" function, or at least modify GameObject class to make it possible?

 

you could define OnEnable and OnDisable messages on that object, then invoke a event other things to subscribe to from it.

 

Oh, right, completely forgot that thing existed. Thanks a lot)
