There's nothing wrong with using a programming based on some factors but the author never explains why these factors matters. Sure, they might seem intuitively right but how can we know that they are really relevant? By the way, Listing 5 is why I love Python: not only does it have far fewer LOC, but it's actually more readable then the other examples, especially with Java, where there's just so much scaffolding going on.
