I think I need to add some constructors that accept data.  std.container  
has some cool construction methods.

For now, can you do something like this?

sl = new ServerList;
sl.add([
    new Server("ServerI", "120.14.220.18"),
    new Server(...)
    ...
]);

The new constructor would probably do something like this:

sl = new ServerList(
     new Server(...),
     new Server(...),
     ...
);

Does that work for you?  If you need to build servers by naming fields,  
I'm not sure that's really a dcollections issue, D doesn't support  
constructing object by specifing individual field names.  Alternatively,  
you could define an external constructor:

Server create(string name, string ip)
{
    auto retval = new Server();
    retval.Name = name;
    retval.IP = ip;
    return retval;
}

BTW, I don't think I've ever constructed a list that way in C#, it's cool  
:)
