So I am writing a Phobos version. This seems to work as requested:


import std.stdio, std.random, std.parallelism, core.thread, core.time;

void main() {
     foreach (m; ["Enjoy", "Rosetta", "Code"])
         task!((s) {
             Thread.sleep(uniform(0, 1000).dur!"msecs");
             s.writeln;
         })(m).executeInNewThread;
}



I have also tried with a parallel foreach, the syntax is cleaner, but to me it 
always print the strings in the given order (so it's not doing what the task 
requires), do you know why?


import std.stdio, std.random, std.parallelism, core.thread, core.time;

void main() {
     foreach (s; ["Enjoy", "Rosetta", "Code"].parallel(1)) {
         Thread.sleep(uniform(0, 1000).dur!"msecs"); // Can't use UFCS.
         s.writeln;
     }
}
