Tom Stoppard quote from The Real Thing: "“What we’re trying to do is write cricket bats, so that when we throw up an idea and give it a little knock, it might … travel … ([He] picks up the script.) Now, what we’ve got here is a lump of wood of roughly the same shape trying to be a cricket bat, and if you hit a ball with it, the ball would travel about ten feet and you will drop the bat and dance about shouting ‘Ouch!’ with your hands stuck into your armpits. (indicating the cricket bat) This isn’t better because someone says it’s better, or because there’s a conspiracy by the MCC to keep cudgels out of Lords. It’s better because it’s better.”

The Apple Mail app preview of my "Better Know A Ruby Thing: Method Lookup" email with the generated summary; "Ruby method lookup order explained; ancestor list created recursively.
In a basic Object-Oriented design, you might have an object called User. This object, by itself, represents the entire concept of a user within the system. In this design, specific states of a user — admin, unauthorized, deleted, subscriber, what have you — are all represented by the single class User. That’s one way to model users. But you could also have the User class be a home for the underlying data and manage some or all of the state of a user by creating wrapper classes like AdminUser, UnauthorizedUser, DeletedUser… even NullUser. At this point, the idea of a “user” is now spread among multiple classes. I’ve started calling this an “object constellation”, feel free to call it whatever you want.
