I think, you can wrap the Task in a class.

abstract class CTask
{
   abstract void wait();
}

abstract class CTask(TResult)
{
   abstract TResult result();
}

class CTTask(TTask): CTask(TResult)
{
   TTask task; //std.parallelism.Task
   override void wait(){ ... }
   override TResult result(){ ... }
}
