 Using POSIX threads:
 <lang Pike>int main() {
+    ({
-	// Start threads and wait for them to finish
+        Thread.Thread(write, "A"),
-	({
-		Thread.Thread(write, "Enjoy\n"),
+        Thread.Thread(write, "B"),
-		Thread.Thread(write, "Rosetta\n"),
+        Thread.Thread(write, "C")
+   }) -> wait();
-		Thread.Thread(write, "Code\n")
-	})->wait();
+    exit(0);
-	// Exit program
-	exit(0);
 }</lang>
-Output:
- Enjoy
- Rosetta
- Code
 Using Pike's backend:
-<lang Pike>int main(int argc, array argv)
+<lang Pike>int main(int argc, array argv) {
+    call_out(write, random(1.0), "A");
-{
-    call_out(write, random(1.0), "Enjoy\n");
+    call_out(write, random(1.0), "B");
-    call_out(write, random(1.0), "Rosetta\n");
+    call_out(write, random(1.0), "C");
-    call_out(write, random(1.0), "Code\n");
     call_out(exit, 1, 0);
+    return -1;
-    return -1; // return -1 starts the backend which makes Pike run until exit() is called.
 }</lang>
-Output:
- Rosetta
- Code
- Enjoy
