I think the point of the examples is to show D at its most 
expressive/concise. The thing is that if you presented "Hello, 
world!" a lot of people who come from other languages would 
complain about how D doesn't seem to have chaining, mapping, 
templates etc. and that the examples are too easy, blah blah. 
We've had loads of discussions about this.

Also, it's good to show people how D code should look like right 
from the start. Whenever I (have to) learn a new language, I look 
immediately at the best practices trying to avoid awkward code.
