Heh, yup :)

I grew up on C/C++ (well, after outgrowing BASIC anyway), and one of the 
first things that blew me away about D was its string-processing.

Yea, I've done the same trick :) Fantastic stuff. But the one issue I have 
with it is that you can't do this:

void delegate()[string] dgs = [
    "name": delegate() {
        // do stuff
    },
    "phone": delegate() {
        // do stuff
        dgs["name"](); // ERR! (Shit!)
        // do stuff
    }
];

That limitation is kind of annoying sometimes. I think I filed a ticket for 
it...

Ahh, shit, it's been marked invalid :(

Yup. Like, totally. :)
