This code makes no output. Why?
Not quite sure, but you could try derived.wait() in main to wait for the 
thread to finish.
It won't help. And method wait() is hidden. I'm using D 2.0.

If you're using D 2.0 then that shouldn't even compile.  In fact, 
std.thread doesn't exist any longer.  Try:

module Test;

import core.thread;
import std.stdio;

class DerivedThread : Thread {
    this() {
        super(&run);
    }

private:
    void run() {
        writefln( "Derived thread running." );
    }
}

void main() {
    Thread derived = new DerivedThread();
    derived.start();
}

Note that if you set "Thread.isDaemon = true" then you will need to 
join() the thread to wait for it to complete before the app exits.
