Ep 047: What is "nil punning"?
Each week, we answer a different question about Clojure and functional programming.
This week, the question is: “What is ‘nil punning’?” We gaze into the nil and find a surprising number of things to talk about.
- “The lowly, magnificent nil. Some people love it, some people hate it.”
- “Null is the value you give your program if you want to see it die.”
- “Nil is not null.”
- “This function found nothing, and I passed that to the next function, and it found nothing in the nothing.”
- “It’s amazing how much nothing you can find in nothing.”
- “You can pull data out without fear.”
- “What does a nil Cat look like?”
- “A lot of arithmetic stuff is nil-intolerant.”
- “No answer isn’t going to start becoming an answer later.”
