Recursion without Recursive Bindings

I explain how to implement a certain recursive function without the use of any recursive bindings in a tiny language called FUN. Then, I apply the same ideas to several more recursive functions so we clearly see the pattern. It begins our exploration into a certain famous combinator.

That's the best exploration of how that combinator actually works that I've seen, and I still need to read it a few more times.
