Hehe. They indeed have similarities - maybe not in language theory or 
overall concept, but in innovation. Having (part of) Ruby's 
expressiveness in D would be a very neat thing, as long as it doesn't 
affect other concepts and goals of D.

That's actually possible already in D (D1, even):

//
import tango.io.Stdout;

void print (char[] s) {
     Stdout(s);
}

void main () {
     "Hello world!".print(); // omitting () is not possible, though
}
//
