Now, you used to have-- there was a very famous cover of The New Yorker in which you had a map of the United States as seen from New York, and where you had New York, and then you had this sort of large ditch that finally--then, Los Angeles was half a football throw away, and everything in the middle was just sort of desert, basically.

And you'll find in the end that recursion is a feature of a language, it allows you to map some very obvious concepts like the phonebook tearing in half and half and half and half to actual code without it using some arbitrary human contrived framework like a for loop or a while loop which are much more stilted mechanisms.
