Interesting technique that I haven't heard of.  However one of my 
friends, a lead programmer at Sega, says they use similar technique 
extensively in C++; actually they avoid overusing it, as it slows down 
compilation considerably.

And for this particular Color case, enum in D can have a base type:

enum Color: string {
     RED = "red",
     GREEN = "green",
     BLUE = "blue",
}

writeln(Color.RED);	// gives "red"

so we don't have that maintainance problem :-)
