How to spawn variable-length functions?

[Andrej Mitrovic]

import std.stdio;
import std.concurrency;

void print(int[] a...)
{
    foreach(b; a)
        writeln(b);
}

void main()
{
    int value;
    spawn(&writeln, value);
    spawn(&print, value);
}

Neither of these calls will work. I want to continuously print some values but without blocking the thread that issues the call to print, and without using locks. Since it's a print function I need it to take a variable number of arguments.

How do I go around doing this? Perhaps I could use some kind of global Variant[] that is filled with values, and a foreground thread pops each value as it comes in and prints it?

Or maybe I should use send()?

I'm looking for something fast which doesn't slow down or pause the work thread.

Multithreading is hard business. :]
