Could anyone please explain to me why the author chose those functions for his examples? I got as far as callFirst() and repeat() and found it hard enough to wrap my mind around the functional / meta programming within. Are those actually good examples? It seems like there are simpler ways to illustrate the point.

If you check out Javascript Allonge (linked on the page, web version is free) you'll find out. The author has written a lot about functional programming, combinators and so on in JS. I think his point was simply that examining how to emulate let/var with closures, it shows you explicitly what is different/similar about them. He's not suggesting anyone use those transforms.
