Boolean combinators

In the Clojure Tip above, I described a kind of Boolean combinator that lets us build complex rules out of simpler rules. Your task is to build those combinators. Please define:

(defn rule-and
  ([])
 ([rule])

Inspiration

Racing the Beam: The Atari Video Computer System

This is the book that got me excited about emulation and got me thinking about some of these computers in general.

Koji Kondo's Super Mario Bros. Soundtrack

I read this around the same time. It talks at length about the audio capabilities of the NES, which I haven't touched on here but are interesting and influential!

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link in the table of content jumps at the copy of the answer on this page.
• The link on the answer itself points back at the original post.
