Passing a value by reference to function in taskPool

[Sparsh Mittal]

Here is a code:

import std.stdio, std.datetime, std.random, std.range, 
std.parallelism;


enum long numberOfSlaves = 2;


void myFunc( ref long countvar)
{


 countvar = 500;

  writeln( " value of countvar is  ", countvar);
}


void main()
{
long count1=0, count2=0;
alias typeof(task!(myFunc)(0L)) MyTask ;


//Possibility  1
        MyTask[numberOfSlaves] tasks;
        tasks[0] = task!(myFunc)(count1);
        taskPool.put(tasks[0]);
        tasks[1] = task!(myFunc)(count2);
        taskPool.put(tasks[1]);
       for (long cc =0; cc < numberOfSlaves; cc++)
       tasks[cc].yieldForce();
//Possibility  2
      //myFunc(count1);
      //myFunc(count2);

   writeln( " value of count1 and count2 are ", count1, " ", 
count2);
}


Possibility  1: Here, I wanted to pass a value by reference to 
myFunc, but when I read that value in main function, its value is 
not changed at all?

Possibility 2: It does what I want.

So, how to properly use the taskPool, so that pass by reference 
works.

Uncomment/comment Possibility 1 or 2 to see the output.
