is there a way for me to do this in D? In java, one is able to create a new instance of an interface.

interface Action
{
  void actions(T t);
}

class testAction
{
  this()
   {
    Action action = new Action()
       {
         void actions(T t){...}
       }
   }

}

I found this feature really useful in java. Is there any way I can duplicate this process, without the mixin func?

There is a somewhat obscure feature which lets you declare and instantiate a class at the same time:

----
interface Action
{
  void actions(int x);
}

void main()
{
  Action action = new class Action {
      void actions(int x) {/* ... */}
  };
}
----
