As well intentioned as I imagine the author to be, there's really nothing here that you couldn't learn from older documentation, as several commentors have pointed out. A more interesting example would have been to calculate running time of some function vs. it's recursive version. Essentially, something besides an extended 'hello world'.

A lot of the stuff you read on here can be found in documentation.. Who the hell wants to go back and read all that nonsense?
