Demeter – It’s the Law!

This post is slightly too much for a tweet.

I have just been skim-reading Demeter: It’s not just a good idea. It’s the law. by Avdi Grimm. I like the message that they didn’t call it The Suggestion of Demeter.

I really liked when i got to the Peter Van Rooijen interpretation of Demeter’s Law. I have never seen it explained quite so effectively!

  • You can play with yourself.
  • You can play with your own toys (but you can’t take them apart).
  • You can play with toys that were given to you.
  • And you can play with toys you’ve made yourself.

Okay, back to work. I just wanted to record that because it was so brilliant. I will read the article in greater detail later.
