To give an example:

class Thread {

   Thread start() {...}
}

class Timer : Thread {
   ...
}


void main() {
   // Timer timer = new Timer().start;  // this does not work
   auto timer = new Timer().start; // because timer is of type Thread
}

Yes:

class Timer : Thread {
   override Timer start() { ... }
}
