Hello world using new dart:isolate

HelloIsolate.dart

#!/usr/bin/env dart 

#import('dart:isolate', prefix:'isolate');

isolateCode() {
  isolate.port.receive((msg, reply) => reply.send("re: $msg"));
}

void main() {
  isolate.SendPort sendPort = isolate.spawnFunction(isolateCode);
  sendPort.call("Hello World").then(print);
}

It was copied from the post http://goo.gl/p3eAf , kept it in only cause it explicitly shows what is being used from the dart:isolate module. Using it going forward I probably wouldn't prefix. Reasons I might would be naming conflicts or displaying explicit intent.
