I have been titled as a Sandi Metz fanboy, I am :). I use "send to" and "plays the role" since I read her book poodr.

If you are looking for actionable hints about how to do OO right, remember those four:

and find here why

the IF keeps us from thinking OO

I also like to quote her on

Inheritance is a knife that turns in your hand
