Casablanca is another new kid on the actor model block. A typical asynchronous accept looks like this:

PID replyTo;
NameQuery request;
accept_request().then([=](std::tuple request)
{
   if (std::get<0>(request) == FirstName)
       std::get<1>(request).send("Niklas");
   else
       std::get<1>(request).send("Gustafsson");
}
