Maybe it's because you haven't added string to the setter? Just grasping

Hi Simen, yes, thats the prob. I just have not found the @property 
docs.. thanks for all the help..
This snippet works now as expected.. D properties are just fine.

import std.stdio;
import std.random;

void main(string[] args)
{
        LoadBalancer b1 = LoadBalancer.getLoadBalancer();
        LoadBalancer b2 = LoadBalancer.getLoadBalancer();
        LoadBalancer b3 = LoadBalancer.getLoadBalancer();

        // Confirm these are the same instance
    if (b1 == b2 && b2 == b3 )  {
        writeln("Same instance\n");
        }

        // Next, load 15 requests for a server
        for (int i = 0; i < 15; i++) {
                string serverName = b1.nextServer.servername;
                writeln("Dispatch request to: " ~ serverName);
      }
