Never ending function

Today, I had a Clojure quiz for myself. How to write a function that print out a number and return a function that will print out an incremented number and return out a function with the same behavior again and again, never end.

For those who are familiar with Clojure might find it easy but for me it took a while and I couldn't solve it so I decided to start solving it with Ruby first.

This is my solution.
After that it was way more easier to port it to Clojure.

I get paid for code that works, not for tests ... - Kent Beck

This quote by Kent Beck is just popping up all around articles I have read these days. Want to keep it  here.
I get paid for code that works, not for tests, so my philosophy is to test as little as possible to reach a given level of confidence (I suspect this level of confidence is high compared to industry standards, but that could just be hubris). If I don't typically make a kind of mistake (like setting the wrong variables in a constructor), I don't test for it
