I assume the purpose for those demonstrations are to win the interest of the user as to how easy and clean D code can be. 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?

How's a new user supposed to know <> is for templates when looking at a C++ example? They don't; it's just something that has to be learned, or they know it because other languages use a similar syntax. Rust uses ! for macro invocation, and I imagine that creeps into some of their examples (OTOH, anything that prints output). Templates are such an integral part of D that any non-trivial example can't get around not using them.
