How do I separate IP parts with dlang?

I found this very cool trick, with C++: http://stackoverflow.com/a/5328190

std::string ip ="192.168.1.54";
std::stringstream s(ip);
int a,b,c,d; //to store the 4 ints
char ch; //to temporarily store the '.'
s >> a >> ch >> b >> ch >> c >> ch >> d;
std::cout << a << "  " << b << "  " << c << "  "<< d;

I wonder what's the equivalent D code.

This would do the same. I wouldn't say it's a trick.

    import std.format : formattedRead;
    import std.stdio : writefln;

    string ipAddr = "192.168.1.54";
    int a, b, c, d;
    formattedRead(ipAddr, "%d.%d.%d.%d", &a, &b, &c, &d);
    writefln("%s %s %s %s", a, b, c, d);
