I assume the purpose for those demonstrations are to win the

Then why;

alias round = pipe!(to!real, std.math.round, to!string);
static reFloatingPoint = ctRegex!`[0-9]+\.[0-9]+`;

How is a new visitor supposed to know "!" is for templates and
not some complicated syntax?
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.
