I think it will be great to have it in language!

But what about:
unittest {
}

It could be just function call with delegate as a last parameter, but in 
the context e.g. of class body it is not possible to call functions...

If there would be kind of static function call (in the context of class 
body) it would be easy to add e.g. to D runtime following signatures:

unittest(void delegate() test);
unittest(string name, void delegate() test);
unittest(string name, string group, void delegate() test);

... or maybe function definition with anonymous, immutable last parameter?

Just a few thoughts...
