I agree.

I don't understand that part. :) The following is the same program with 
just two differences: prompt() takes a pointer and 'server' is a pointer.

import std.conv;

struct Server
{
     string name;
     string ip;
     int port;
     string user;
}

string prompt(Server * server)
{
     return server.user ~ "@" ~ server.ip ~ ":" ~ server.port.to!string;
}

void main()
{
     auto server = new Server("bzzt", "192.168.0.1", 80, "nobody");
     string p = server.prompt;
}
